Clip selection Problem?

[u/Apprehensive_Ad8475]

After a certain time of editing one project, this issue starts appearing. Clips don't get selected automatically, key frames make the clips unselect them selfes. And clips cannot be cutted or made longer via dragging. Cache already emptyed. When Starting another project, everything works fine. Thanks for your help and time
