Importing Categories Doesn't Import Both

I am running into a problem here. My shop is in two languages; dutch and english. However when I export my categories and then import them all I am left with is either the dutch language or the english language (depending on which language I chose when exporting).

I also tried exporting the dutch AND the english language (even gave the csv files different names) but all that does is placing both languages together under the catalog > categories tab. Instead of having the one as a translation of the other.

Can't cs-cart export/import categories in both languages?
