Does anyone know why the foot roll snaps when I adjust it in the control rig?

I am animating the control rig, but the foot roll seems to snap back and forth like this. In the animation details it is also greyed out. Does anyone know how to fix this or what the cause is? It is very hard and annoying to animate like this:

Never mind, it is because I opened the Locodromepicker window and when I minimized it the problem stopped.
