Action layout switched from right to left?

Hopefully this is a quick simple one someone knows the answer to. My Surface properties always sat on the left and Axis properties sat on the right… I think ive pressed some sort of hotkey and now its switched to Surface on the right and Axis on the left… Anyone know how to change this back??? My brain can’t cope with the change haha

Did you switch from Dual to Single?
