Running Software (please complete the following information):

• Game patch 8.1.5 (29981) (Release x64)
• 8.1.9

Describe the bug
Some of my characters can sort the reagent bag, but most cannot. The main bank bags seem to sort ok, but the reagent bag will not.

To Reproduce
Right click on manage bank

Expected behavior
Grouping of items in reagent bank and sort

I am experiencing the exact same issue as the OP. Very frustrating.

Experiencing the same issue as well. Some characters can sort and some can't.

Having the same problem. Running the same versions as @zaldor29.
