China Brazil FTA can display the header with HK and Mainland

The first time we met this situation, we are confused now. Our company's goods are mainly exported to Pakistan. Before, the goods were sent to the designated freight forwarder's warehouse after the goods were ready, and then they were shipped by container. But this time, this customer asked us to provide China Pakistan FTA certificate of origin, so we asked the freight forwarder to take the China Pakistan FTA certificate of origin, but they told them that the certificate of origin issued by them was in accordance with the The whole container came out, and the title of the certificate of origin was not our company, so we couldn't provide us with the certificate of origin of China Pakistan FTA. Later, we found an agent to do the certificate of origin, but the agent said that the title of our original bill of lading had the words HK and the address of the mainland. They couldn't handle it. They could only issue either the name and address of the mainland, or the title of Hong Kong and the place of Hong Kong Address, do you have any solution to this situation?
