At launch I bought the collector's edition, with BLES-00901 and its gamedata and save games have [UK] in the name. But today I went and got the Ultimate Edition for the DLC stuff, but it installed everything in French. It's BLES-01745 which I think should be correct for my region and should work with 00901 save games right?

The sony install screen was french, the game, even the gamedata has [FR]. It of course didn't recognize my old save games either and there's no language selection anywhere. Both discs are bought in the Netherlands in reputable retail shops (Bol.com and Dixons), so I shouldn't have any weird region-specific issues.

Can anyone confirm I've got the correct BLES-versions that should work together? And why would the Ultimate Edition disc install in French? The cover says it contains English, although the 2-page booklet is mostly French as well.
