Different bank account for different currencies

Hello,
I am seeking a little guidance on bank accounts linked to Amazon. I have 2 currency accounts.
GBP for .co.uk & EUR for .de, .fr. .es and .it
I receive GBP proceeds in my GBP account linked to .co.uk account.
But for some reason I cannot receive EUR payments from other 4 portals in my EUR account. Every payment cycle Amazon tries to make EUR payments and says they were unsuccessful and then removes my bank account from the ‘Assign a bank account’ section. I have then go and re-assign them, all the while not receiving the payment.

Both accounts belong to same bank and are based out of UK. Just their currency denominations are GBP and EUR.
Do I have to get a EUR account based out of Europe.

Anybody here seen this before? How can I link different currency accounts?
Seller Support are unable to help.

Thank you & regards
