Augment buff slot weird fuction

Hi, when I buff with augment skill it doesn't take any buff away, but when I add another buff on top, it starts counting as +1 buff and removes 2 buffs from me. Am I clear?

Sounds clearly but I can reproduce situation as you described.
Short video or at least screenshots can help little bit more then just description of it.

I saw what is going on, when you get cancelled, when buffs come back, augment takes 1 slot and you receive one less buff.. trying to get pics.. please check it
