Apple Wallet won’t let me transfer Apple cash to bank

Wallet won’t let me transfer apple cash to bank. It says to add wallet (it’s already in there) but when I go to add it it then tells me it’s already in there. But then it goes back to saying I have no card and to add one but when I go to add one it says I already have one. Help it’s so frustrating
