MacBook Air / Apple M1 macOS: Ventura 13.4 Hello, I have recently started using KDENlive and I have the problem that I can´t delete the effects I have used. I have already tried the following steps: 1. Right click on the inserted effect in the timeline. Then a window opens and I can click on “Delete effect”. However, the effect is not deleted, but the clip/sequence is marked. 2. Mark the effect in the timeline and then click on “Clip”. The “delete effect” function is not selectable there. 3. It is not possible to move the effect to the trash under “Properties” because no trash symbol is displayed there. 4. Shortcut "Delete" does not work either.
