AirPod Pro Fit Problem

I get a perfect fit (seal) with all three sizes in my left ear, but none of the three sizes gives me a good seal in my right ear (according to the fit test) unless I physically push the airpod into the ear and hold it there during the fit test. Then I get a good seal. Obviously I can’t do that on an on-going basis. Is this a me issue or an air pod problem? Any suggestions or am I SOL? Thanks so much!
