Emulation Cemu online, country flag

[DebbySaurus]

I've recently dumped my Wii-U files to enable online mode for Cemu, but the game show an American flag next to my name instead of my actual one (netherlands)
On my real Wii-U itself it shows the proper flag.
In this case it's Super Mario Maker.
Did I do something wrong or does it have something to do with my Cemu settings?

probably cemu settings that indicates you made a account with american settings

Any clue what file to edit to change that?
Changing my emulator region and language didn't help.
