That was my first thought, but reading the OP again it seems they are describing that the debuff is switching from light to dark or back the other way, while also keeping the stack count, which isn't how the fight should be working even if they weren't switching on time or switching back before it has a chance to register.

@OP - is that what is happening? You're switching to the other side, the debuff changes color, AND it keeps the stack?
