Odd issues after FW 3.6 upgrade

Hi All,

I upgraded to 3.6 and MMU2 to 1.05 but accidentally installed the FW for MK3 MMU2S. I loaded the correct but don't know if this caused the issue or something else.

FW 3.7 fixed issues with filament loading in MMU2.

Problem 1. When printing a small part I'm getting I think a retract issues. It shows in the same general area either inside, or outside (if check box set to print external perimeters first). I tried a different model and did not get the defect, so I tried repairing it, regenerated it in CAD software. All do the same thing.

Problem 2. Just noticed that the first LED on the MMU has a very slight flicker. i recorded in with phone and you see if some, but some more than you can see in video. The selector is in the 2nd location, led for 2nd location is on. First location LED (right side) is the that flickers, almost like noise in the system or program. I program Arduino and I have seen this behavior before.

Thanks for any suggestions, I'm all ears and willing to try different ideas.
