Unable to buy from vendor with currency in currency tab

This happens at random times during every league and it's very annoying. Usually happens after I move around stash tabs some day, and then the bug exists for the rest of the league.

Scenario:
I try to buy an item or use a Kirac map craft with no currency in my inventory, but the required currency in my stash (my currency stash tab).

I get this "You do not have sufficient currency to buy this mod.":


The state of my stash when I click on it after seeing this (currency tab not selected):


Selecting my currency tab to show that I have ample currency:


After selecting the currency tab once, the vendors tend to fix themselves and pull currency from my stash appropriately.

Not a bug.

Move your currency tab to one of the first 5 or 6 tabs. Only those tabs get indexed when looking for currency for vendor purchases.

Edit: :P

this isn't a bug, the game only preloads the first 4-5 tabs, in this case your tabs for sorted heist stuff and dump tab.

just move your currency tab to be the far left tab
