Reply to Modifier Bug?

Hello Guys!

I'm not quite sure about this, maybe I'm doing something weird but here it is:

I mapped as follows:
Modifier #5 hold set to 3 (no modifier condition)
Modifier #5 direct set to 2 (no modifier condition)




When I map it I can get one of these results:
a) Gets stuck in 2
b) Goes from 0 (not pressed) to 3 (holding it)
c) Goes from 2 (not pressed) to 3 (holding it) when I press it

If I delete the mapping and redo it, that sometimes change the result

This has been bothering me for several days. What I want is "c)", or does anybody know some other way to get the modifier to work as I want?
