Unclickable Edit Page Track Buttons

I've been running into an issue on the Edit page recently where the "Auto Track Selector" and "Disable Video Track" buttons, or "Mute Track" for the audio tracks, become unclickable on all tracks. However, I can still lock and unlock the tracks as well as make edits on them. For the audio tracks, the Mixer's mute button still works as well. Restarting Resolve fixes the problem. It's happened a few different times but it's not been clear what triggered it.

Possibly related: I had an issue on the Color page for the first time just a moment ago where, after renaming a node, the whole node graph appeared to freeze. It seemed to be only the display of the graph, as I could still move through the nodes with the micro panel and all the other displays and controls worked normally. I attempted to refresh the display by selecting "Clean Up Node Graph" from the context menu. There was no change to the display but I noticed after restarting Resolve that it had, in fact, rearranged the nodes. Restarting fixed the issue.
