most likely the axle is protruding beyond the dropout. so the QR is clamping against the dropout a little and clamping against the axle too. you dont want it clamping against the axle, just the frame.
FIX: big washer around the axle. do it on the side it slips. bit of a bodge but its a fix
otherwise file the axle down or space it out more.
