DSers‑AliExpress Dropshipping

I've been using Dsers for many years, but recently I've been having problems every day when placing orders... Now I literally can't process ANY order, with the following error message: "AliExpress found a CPF issue. Contact your buyer to check CPF accuracy "

All orders with the same message, all of them! There's nothing wrong with the customers' CPF, it's a bug in the platform that no one solves... If anyone can help me I'd be grateful, as I have hundreds of orders to send!
