Selection Follows Playhead broke?

I've noticed the menu option Timeline / Selection Follows Playhead isn't working for me any more?

I'm running on 17.1B, build 21 (AKA "DaVinci Resolve Studio 17.1 Public Beta 10").

I didn't see a way to post this in a beta section. It seems to be locked.

Also, pressing "x" on the Edit Page, is no longer selecting the current clip. Rather, it's selecting a much larger area on the timeline. Pressing "x" on any clip on the timeline has the same effect.
