Screenshot 8: Proof that the audio is no longer recognized

SUMMARY:
My English is really not good so please don't be too mean to me :D

The .kdenlive file is 3.2 megabits in size. Since yesterday, when I open my .kdenlive file, I get a bunch of error messages (screenshots 4 to 7). The last error message reads:
"Some errors were detected in the project file.
The project was modified to fix the conflicts. Changes made to the project have been listed in the Project Notes tab,
please review them to ensure your project integrity."
These errors result in large parts of the video project (i.e., all five main parts or sequences that make up the video, which are marked with positive numbers; the sequences with negative numbers are irrelevant) having no audio track or having disappeared. At first, it seemed as if the original MP4 file was corrupted, but no, it isn't. In screenshot 2, I demonstrated that I had indeed inserted the original MP4 file into the video track again, and it is displayed with sound. The sound also plays back normally and can be edited normally. So, using the exact same element from the project content.

(See screenshot 8)
So that's how it was until I tried to fix the error. I right-clicked on the affected clip in the project content and then clicked "Transcode to Edit-Friendly Format." I then hoped that "Replace Clip" would fix the problem, but then things somehow got worse. Suddenly, the program no longer recognizes the audio from the clip at all. I can drag the video into the timeline, but the audio track from the video remains missing. I can insert the original MP4 file without being informed that the file is actually already present in the project content. I can apply what I just described to this new clip.


Here's the text and headline again, but in my native language, because I used Google Translate for the English, and so the meaning of some sentences is partially lost. Maybe someone here speaks German, idk.

Ohne ersichtlichen Grund wird die Audio von mehreren Videos nicht geladen:


Die .kdenlive Datei ist 3.2 Megabit groß. Seit gestern ist es so, dass wenn ich meine .kdenlive Datei öffne, ich einen Haufen von Fehlermeldungen bekomme (Screenshot 4 bis 7), die letzte Fehlermeldung besagt 
“Some errors were detected in the project file.
The project was modified to fix the conflicts. Changes made to the project have been listed in the Project Notes tab,
please review them to ensure your project integrity.”
Diese errors haben zur Folge, dass es bei großen Teilen des Videoprojektes (also bei allen 5 Hauptteilen bzw Sequenzen aus denen das Video besteht, und die mit positiven Zahlen gekennzeichnet sind, die Sequenzen mit Minuszahlen sind hierfür irrelevant.) keine Audiospur vorhanden ist bzw diese verschwunden sind. Es machte zuerst den Anschein, als wäre die originale MP4 Datei beschädigt, aber Nein, ist sie nicht. Bei Screenshot 2 habe ich demonstriert, dass ich wirklich die originale MP4 Datei nochmal in die Videospur eingefügt habe und diese mit Sound angezeigt wird, dieser wird auch ganz normal wiedergegeben und ist normal bearbeitbar. Also über das exakt gleiche Element aus dem Projektinhalt.

(Zu Screenshot 8)
Also so war es solange bis ich versucht habe den Fehler zu beheben, ich habe nämlich im Projektinhalt beim Betroffenen Clip Rechtsklick und dann auf “in bearbeitungsfreundlicher form transkodieren” geklickt und dann gehofft das ich mit “Clip Ersetzen” das Problem zu beheben, aber dann wurde alles irgendwie schlimmer. auf einmal erkennt das Programm die Audio vom Clip gar nicht mehr bzw das Video kann ich in die Zeitleiste ziehen aber die Audiospur vom Video bleibt verschwunden, und ich kann ich orginale MP4 Datei einfügen ohne darauf hingewiesen zu werden das sich die Datei eigentlich schon im Projektinhalt vorhanden ist und das eben beschriebene kann ich bei diesem Neuen Clip wieder anwenden.


STEPS TO REPRODUCE
1. Add MP4 file in "Project content"
2. This file has a total of at least 393 cuts across 5 sequences. (Maybe the same thing is happening to you, idk)
3. If necessary, repeat the situation in the second section (maybe the same thing will happen as it did for me, idk)
