fuji 6x7 Mk 3 problem

[lindyhopper]

I put a roll of film through Fuji 6x7 Mk 3, but I had not noticed the frame selection dial was between 10 and 20 exp, now when I put new roll in camera,the frame counter starts at 12.
Is this an expensive repair job or is there something I can cure.

It thinks 220 is loaded. No idea on fixing. You could check if it's set for 120 or 220.
