Issue with EU vat postings

I have an issue at the moment in that my last VAT return included supplies to other EC states, which I do not do.

I have checked the calculations and it all relates to one client, however when checking the client details the section for VAT registered in another Member State is disabled - I cannot see what I can do to get the correct VAT return.

I think that client would have been flagged as an EC when the invoices were created, unflagging the client doesn’t remove the EC flags at the invoice level. It’s probably easier if I send you a PM to get the relevant information.
