Problem with round-robin mouse button

Hello,
i made a round-robin mapped key for mouse button 5.
Sadly it doesnt work, it execute the round-robin action only on 1-2 of my 4 characters and then it seems to stuck and start on the first character again.
I have this problem only when i use round robin on mouse buttons.
Is there any way to fix this problem?

My first thought is that this might be happening:
FAQ: I am using a mouse button as a hotkey for something, and sometimes it doesn't work, what am I doing wrong?

Now i use mouse 5 only to execute the mapped key and changed the ingame button to a different key.
Now is works perfectly, thank u very much.
