Timeline jumps when trying replaying from a specific point

Hello everyone

I've been having this really aggravating issue with the timeline, and it's finally irritated me enough to see if any of you have any insight/suggestions into how to fix it.

I am working on queuing objects with audio. Once I think I have each object queued, I click on the timeline before each layer is supposed to appear play the slide just to make sure it is lining up correctly. When I do this, the playhead will actually jump back anywhere between 10 and 20 seconds from where I clicked to start it. This is really aggravating and wastes a lot of time.

Is anyone else having this issue or can anyone give me any insight on how to fix it? Thanks!
