Fader automation questions

I updated to 3.11 before Easter and I am now having trouble with my fader automation. The faders move just fine but the real world output jumps. I have several faders of different LED fixtures and as they are fading, either up or down, the LED intensity will follow then jump to another intensity (either 100% or 0%) then jump to where they are supposed to be. Plus, it is difficult to recreate the problem since it happens at different times during the show (one time it will work, the next time it glitches,, the next 5 times after its fine, and then the 20 times after that it glitches again).

Also, is there a way to interrupt a fade macro in the middle of the execution of the command? Sometimes the fade doesn’t fit even after rehearsing it the same way several times. I would just like to be able to interrupt or hold a fader in mid change to keep it from going to far.

Thanks for any help/ may have.
