Yes, it dose seem like the French lost a bit of territory.
True, and a lot of Frenchmen are annoyed: but the RC's Dutch allies wanted some payback for historical humiliations, the German members of the Confederation wanted an independent Rhinelands, and the Confederations leaders are no more geniuses of foresight than the folks at Versailles OTL...I mean, it's not like France lost French-speaking majority areas, right?
(Or are you just opposed in principle to France losing any territory? )
