Unexpected and bizarre behavior in Pr is corrupted prefs 99% of the time (in my experience since CS 5.5).  Launch the app with the option/alt key pressed.

Other routines: delete all caches and previews.  

Corrupted sequence is another possibility.  Create a new Sequence.  Copy the old one and paste into the new one.

Corrupted project is another possibility.  Create a new project, and import the old one, or drag everything from the “bad” project to the new one.

Uninstall and reinstall the app if all else fails.

I see two instances of Ultra Key in your screen grab with the Effects tab.  Could that have something to do with your issue?
