The Klingon Empire's planet is selected, but it shows the Orion Syndicate (and vice versa). That's only an Issue when selecting all races. It's an issue in several games with many races, and it seems to be a random issue with different races. If you choose "Minors" or "main" races, everything is correct (after some loading time). It's a game with many (custom) races, so that might be an issue.

There are invisible icons at the shipyard to select "user", downloaded" or "core" ships.
German localization, issue with small and normal UI (and probably every other UI), 1080p
I followed all instructions at

but that made no difference. The problem still exists.
