Revolter breaks after a few action skills

The revolter with ASS anointment is only lasting a few seconds, the shock damage disappears a few shots after using the action skill. I’ve tried this on pc with zane’s cannon and on ps4 with fadeaway. The electricity graphical effect on the side of the screen lasts the full 15s but not the damage.

The effect last 15 seconds and won’t refresh while active.

Then when it ends it should last 15s when used again, it’s not doing that.
