Account data is cleared for no reason

One of my accounts, yanwuxin1234, was transferred from the Western European server to the Russian server. After the completion of the transfer, my experience, hero, skin, etc. all disappeared, leaving only the essence and guarding the skin. I don’t understand why this is the case. The specific situation is as follows: After the transfer is completed, I successfully landed in the Russian service, and the level is 52, the skin hero is intact, but flashes back in less than a minute. When I log in again, let me recreate the role name.But no matter what name I created, the system will prompt that it is not available. I can't wait for the next day. I just created a name and went in. I am waiting for a newbie task and a first-level empty number. I don't understand why the system is like this, and my record of training in the Russian novice training will appear in the European service. This is very strange. I hope someone can come out and tell me why, because I have been waiting for myself for many days.
