20 Beta 3 - Can't Reset All Grades and Nodes - Dual Monitors

With a Dual Monitor setup, I can no longer Reset All Grades and Nodes on any of my clips. Also, Apply Grade (from Powergrade) still does not work. Works fine with single monitor setup.

Same with me, triple monitor setup and "Reset All Grades and Nodes" doesn't work

At my end, I've noticed that it happens when I change the Display layout in System Settings and then adjust the Dual Screen layout accordingly in Resolve. At that point, I can't Reset Nodes, nor can I Apply Grades from a Powergrade etc. Restarting Davinci seems to fix it.

I found this issue was happening because the 'Sizing' dropdown was selected by default in the Keyframes panel. When I changed this to 'Color' or 'All' the issue goes away and I can reset nodes and apply powergrades correctly.

Not sure if this is something to do with this project or my preferences, but glad I figured out what was going on.
