There's no beta program for me her in steam linux.
You have to unlock it. It is explained in the following thread:

I'm also on PC - Windows 7 64 bit - Steam.
I think it's the same for me.
I'm using the German-Translation mod.
I tried to verify the chache and changing language back to english, but it didn't resolve the issue.
PS: Thanks for the update
Hmm I'm new to this forum, did the devs say something about this bug beeing fixed in the near future? Becase in that case I think I would stop playing for some time. It's not game-breaking, but pretty annoying.
(I also used the german mod btw. )
Hm this is pretty annoying. Is it just in the first town or will the bug occur later in the game? My Prices at the Black Hammer Smithery are inflated but the ones in the Black Hound Inn are fine.
