Strange URL and country

Guys, I keep getting issues with some strange translation of NEDERLAND.

I deleted all posts, deleted all relevant listings in the database, but still its unpredictable and strange.

It looks that if I change DEFAULT country to enable multi countries that most listings seems fine. especially in events and custom post types. The problem keeps in places. I’m pretty sure that i have translated the countrienames well in the PO-file.

If I ad a new place i get an error on the frontendform, that says: select a country. That’s not possible of course because i’ve set it to default.

But then in the translationstab of manage locations the countryman changes to NETHERLANDS.
So then I select the button and i confirm to translate it and then country-url AND country-url after translation change to:

%ef%bb%bfnederland.

I want to start filling it with real data, but it feels not comfortable like this.

If you have time to take a look… appreciated a lot!
