Staffing and floating

So I've been a floater for 2 months now and my district supervisor hasn't mentioned giving me a staff position however all the others in my intern class that I started with have been given stores. I'm not sure why. Is it possible my pharmacy supervisor sees some fault in my work? I make mistakes, I'm not hiding that fact but to my knowledge it's never affected a patient. I'm not sure if I should ask him or not.
