Ask your question othe relevant EU government authority that provides law advice for all EU citizens:
EU rights - advice and problem solving
I used this free service to get a handle on a few of my local laws.
And my common sense advice is to not sign it, as you will probably take the fall. Especially if it's easy for government employees to discover this discrepancy - they usually don't like to report the little stuff but if it's that obvious they have to report it or risk trouble, they are also human after all.
Better to find another job that risking ending up in jail. Or just amend your copy and sign the edited version.
And keep copies of anything that can be your evidence if all hell breaks loose.
