Very odd indeed. According to the Finnish Gun Proof Act (27.8.1982/656) every firearm manufactured or professionally repaired in or imported (unless already C.I.P. proofed) to Finland and intended for sale should pass gun proof according to C.I.P. regulations.

I would be inclined to suspect the Finnish proof house. It operates under Finnish police board's weapon administration which is full of criminal idiots that harass law-abiding citizens. Maybe even the proof house has some incompetent rats on the payroll.

Did the rifle in question have the Finnish lion's head proof marks?

Have no idea why Sako should lie about Finnish proof requirements though.
