So i'm adding an animation effect... For example a 'Question Mark'. To the beginning of the video.
There are mutiple segments and tracks already.
Then when I drag another 'effect' --- like a Deco-'Film State' to a later piece of the video. Then I find that the earler 'Question Mark' has dissapeard.
So then I try it in reverse, and even zoom out so can watch this 'deletion' take place. It's as if I can only have one 'effect' on the video at one time.
If you need a video-capture of what I'm seeing, I can provide.
