I'll try to cut out part of my mapping later and show it here to find my mistake.
What you describing is a clash situation that happens when two different commands are trying to light up the same LED because the LED is mapped to all conditions.
Example: Some assumptions made to illustrate the point
Say that you are trying to switch between player 1 (A) and player 3 (C).
There is also a button that when pressed it activates shift logic 1 (ML1) in order to control player 3.
At this point you switched from player 1 to player 3 and your sync LED for player 1 is mapped to:
1. work with no condition for player 1.
2. work with condition ML1 for player 1.
3. work with no condition for player 3.
4. work with condition ML1 for player 3.
This mapping will behave exactly as you described. The same LED is mapped to work under player 3 control using ML1.
There is a clash.
In order to make it work correctly your sync LED must be mapped to:
1. Work with not condition for player 1
2. Work with ML1 condition for player 3
In this way if you are in player 1
sync LED works
Then switch to player 3 by using your ML1 switch
Sync LED turn off momentarily and then starts displaying according to the control commands of player 3
Then you switch back to player 1.
Sync LED turn off momentarily and then starts displaying according to the control commands of player 1.
