Whenever I kill a mob with a skill, at the end it gives 2 basic attacks. 

I kill a mob with the skill and my character gives 2 basic attacks when he is already dead.


why?

This only breaks my sword!

Anyone knows how to solve this?

It happens to me using these skills for example:


Shatter armor in axe
and
strangle strike in sword




with basic skills this does not happen to me: basic beating, advanced beat, great beat. etc.

HELP!
