Whirling slash issue with movement

Is there a setting to make whirling slash work?

I play PC - When im at my hideout it works flawlessly, i can hold my mouse button down and Q (the button assigned to WS) and he continuously moves forward using the move over and over. The second i get into a map and near enemies it discontinues the move and i have to constantly bash the Q key to get him to use the skill... What is preventing me from not being able to just hold the key down like in my hideout? any help is greatly appreciated.
