Co receiver country display problem

Hello, we made a general certificate of origin CO in a single window and sent it to UAE. After declaration, the certificate has been returned. The reason is that there is something wrong with the country of the consignee, but I wrote the information of the consignee very clearly. The country at the back of the address information is also the full name, which is also written according to the country of the certificate of origin, but the certificate has been returned. What should I do?

0323 -- the receiver's country is not filled in or the spelling of the country is wrong. If the importing country is a member of the European Union, the country of the consignee can be any member of the European Union. If the importing country is not a member of the European Union, the country of the consignee shall be the same as that of the importing country.
