Stash Tab Affinities don't work anymore

Since today stash tab affinities don't work for me anymore. The tabs (eg currency tab) are still marked in the tab selection but the affinity doesn't work. Disabling and enabling the stash tab affinity didn't help.

I tested it with currency, fragments, and maps.

The only unusual thing i did today was that I accidently changed the language of the client. Not sure, whether it is related.

Ok, apparently I managed to somehow disable the "Enable Tab Affinities" stash tab setting. Please excuse the noise.
