Trader doesn't recognise cash or items in Stash

Attempting to buy or barter items from traders doesn't work.

The traders do not seem to recognise that the cash or required barter items are in the Stash

(the items and cash are definitely in the stash and not on the character).

Attempted ticking the box for Fill Items but would not do anything.

Attempted closing and restarting the server but no change.

Any assistance appreciated!

Will try tonight. I'm curious why it isn't recognising rubles though which is an amount that changes regularly.

No joy with adding items
