Payment in extenstions sort the list erroneously

It sort OK the first methods, but then it "flipts out" and show the same the rest of the list?
Pls check the attached pic

And which links do you see, if you hover these Klarna checkouts? Are they also the same?

That means you're missing language files for those other payment methods. One bug is that the admin language doesn't always determine that list, so if you've changed your front-end language to something else, and are missing those language files admin-side, it could be the cause of the error.

Make sure you have valid language files for all payment methods you have installed, and try switching your default admin/front-end languages to see if that has an effect.
