my problem is, that one of my clips in the timeline is replaced with another clip after saving -> closing -> opening the project again. after lots of testing i renamed the clip. since then, it seems to be work and this clip would never bei replaced after reopening the project. is there a probleme with my file-names? you can see the problem on the attached screenshots.
screen one: before closing the project
screen two: after save -> close -> open
thanks for your help
