Invalid IBAN with Romanian bank

Hi, with Romanian Raiffeisen internet banking I get an error related to Revolut IBAN (trying to transfer to Revolut account):
2 Caractere Ramase
meaning 2 Remainiog Characters
meaning the provided Revolut IBAN is shorter by 2 characters (Revolut IBAN is 22 characters instead of the 24 ones required by Raiffeisen).

What should I do about this?

You need to talk to your bank about this. The Revolut IBAN has the correct length for a GB IBAN.
