PoE 2 Bugged Stash Tab?

So I decided it was time to fix my tabs after throwing everything in a single tab and noticed that there's one which is coloured brown and won't allow me to chance the colour, name or untick affinities.



As far back as I can remember in PoE1, I've never had a similar issue as I've always been able to alter all of them but this seems to have snuck in or changed at some point in PoE2.

Is it a standard tab? Bugged tab?
