OK my CSC is:
CSC: N9005OXXENA5
That CSC came up as from these areas (Hungary, Poland, Baltic -)
The PDA is the same as the AP number in that code.
It shows that KitKat is already out for that CSC, most are now, and you say you have it anyway.
Why it has French I don't know, maybe it was destined to be imported to a supplier there, but it doesn't matter, all countries will be the same in that region locked area. in case you don't have an EU region lock sticker on the box, remember you can only use it in a different world area when travelling only after you have used a local EU sim for a few days for some calls texts and data (apparently). Regards.
