Doesn’t Work – Video Editor Pro: Merge Videos Review

Whenever I add text or anything to a video, when I try to go back to edit a different video, a little wheel pops of and says rendering for half a second and then disappears and it will not let me leave that video and go to edit a new one. I restart the app and I’m back to the screen with all the videos, but the changes I made did not save. Does anyone know a fix to this bug
