Friend entered six codes but has no Golden Keys?

hello

A friend I play with who both of us did the pre-order and have shared Shift Codes is not getting…at least not showing…Golden Keys at the bottom of her Backpack (next to Eridium). I’ve got (12) which is about right yet she said she’s only got (5) and those were from the pre-order bonus. All the ones she has entered…and shows a green check mark when completed…are not showing up at the bottom.

Anything she can do or double check on?..Does she need to fill out something or actually request help? Thanks
