Barb just stand on ground saying " The skill is not ready" after FC

My barb is using Furious charge and Ground stomp but he just stand on ground after using FC skills saying " The skill is not ready" very often. I also use Call of Ancients. I tried to use Sprint instead of Ground stomp and same thing happened.

I think he is trying to use Call of Ancient but the skill is not ready. He could use Furious charge again but he just waiting for Call of Ancient ready.



Did anyone has same problem and solved? Could you share how to solve the problem?

Thank you
