Kdenlive's sources dropdown after selecting a different source a few times

SUMMARY
When selecting a different source on an application, sometimes Discover will slightly hang, and then when everything appears normal, the sources option has duplicates. This can happen in sequence, and seemingly resets after closing and restarting Discover.


STEPS TO REPRODUCE & OBSERVED RESULT
1. Open Discover and select an app (I personally experienced this with Kdenlive).
2. Select sources; none of them will be selected, and the top one's radio button will seem slightly deformed.
3. Select the ubuntu-jammy source. Discover will hang.
4. Select sources again: there are duplicate ubuntu-jammy and flatpak sources.
5. Select the flatpak source. Discover will hang.
6. Select sources again: there are another set of duplicate ubuntu-jammy and flatpak sources, and a new snap duplicate.
7. Select *one of* the ubuntu-jammy sources. I say "one of" because some will do nothing, but there is one that will duplicate everything again.
8. Continue. On every refresh of the sources, there will be one source that triggers a duplication.

EXPECTED RESULT
The source simply changes

As an additional comment, this is *not* the first time a KDE application has behaved strangely. I once tried to download Krita from the packages and opening it created enough windows to fill out my panel, and every instance crashed. it then continuously restarted itself, even after removing it, and I had to restart my computer.

Yikes!

However I'm afraid Plasma 5.24 is unfortunately no longer eligible for support or maintenance from KDE. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. Please update to Plasma 5.27 as soon as your distro offers it to you. If you need support for Plasma 5.24, please contact your distro, who bears the responsibility of providing support for older non-LTS releases.

If this issue is still reproducible in Plasma 5.27, feel free to re-open this bug report.

Thanks for understanding!

Makes sense! I'm using Kubuntu LTS so I'm a bit slow to get new Plasma versions, which kinda stinks. With classes it doesn't make sense to switch distros right now, but come winter break I might take the opportunity to find something that has better access to newer Plasma versions. Might even give Neon a second shot! Though I also like the idea of an immutable distro, so perhaps BlendOS might be something I try.

Thank you for the response! Unrelatedly, how can I view all the bug reports I've made in the past, even closed ones? I could only get back to this thread via an email I'd received.
