I hear you, Jill. Experimented with your findings and was amused that I’d never noticed that behaviour before.
Well, the only solution I’ve found is to drag the 2nd clip (currently underneath) to the right, and then it pops to the front. Not really helpful, since no doubt you wanted the 2nd clip more to the left, but can’t see any easy solution if not wanting to add tracks…..
also, it makes sense that the 2nd clip WOULD be under the older clip, since it is trying to create a dissolve / transition.
