Removing/Unequipping a skill?

[Mograx]

I have a warrior pawn, and after trying out a charge up skill, I've decided I don't like it and want to remove it from her equipped skill slot.

There's no button or ability to remove or un-equip skills that I can see. Is it not possible to remove a skill once its been set?

I'd rather not replace it with another skill either, as I don't really have one to replace it with, just more charged up skills, which is the reason I want to remove this one.

What's wild is I can't find anything on google that resembles this question in any way, so apologies if this has already been answered.

Set skill, select skill want to remove, select - . You can even set no skill.

At the very bottom of the skills to choose from you can set the dotted line to "empty" the skill slot.
