I have a client in Denmark who has paid their invoice twice. I was able to post the original payment in Danish Kroner DKK to my Danish Bank in DKK. The clients card is setup with DKK as the default currency as is the bank account I want to post to.
When I try to post the overpayment I am unable to select another currency other than the base currency. The option is greyed out and I get an error and can't proceed.
I have attached screen shots showing the problem.
