How to change the first and last name of a profile

 
I have an account, have uploaded my ID for seller registration and have been approved.
The name Da Xi Hong in the image is not my name.
I haven't entered it, but it seems to be set.
It cannot be changed by graying out like the image.

Please tell me how to change it.



 
You are a verified seller and you can change your details through the Service Desk only.
 
Thank you very much.
