Unity 2020.3.1 Timeline bug

Hi,

I'm working a project using a timeline and the problem I am having with it is that when I set the timeline to 0 and click off the timeline object the world resets to a random time in the timeline. Reselecting the object with the timeline and the timeline window open changes the timeline back to frame 0 but when unselected again it goes back to the random time again.

This random time changes sometime but I haven't figured out what it is that is changing the timeline frame it is going back to.

Here is a video of the timeline selected and at frame 0 and then clicking on another object and having the world go the random frame.

Any help would be most appreciated. Thank you
