Alva/Currency Exchange "I Have" vs. what is in Stash is not updating correctly

Nothing game breaking, but annoying:

Sometimes when:
1) I open up Alva's Currency Exchange
2) Click on "I have"
3) The "I Have" menu/list is not showing everything I have in Stash. It shows some, but a lot seem to be missing.

So then I will need to open up Stash and browse through stash tabs where those specific missing items are located. Only then will the Currency Exchange's "I Have" menu show the real stash inventory. So it appears the "I Have" menu inventory is updated only when the stash is opened and browsed before hand.
