Hey, store page list 24 different localizations while in-game interface allows selection from 9. Which one is correct?

The game.

That is a bit sad, I was sort of hoping this is some kind of bug.
I mean i can perfectly fine play EN version, but would be fun to have it in my local version too.

Not to mention GOG exposing themself for false advertising claims

Imagine that! LOL

I just found out on developers Discord that more localization files are being reworked after recent big patch.
However that seams to be a community effort to provide all the versions. So it may take some more time to get them but they are planned to be back.
