Should the user name exactly match when generating the private key?

The iOS debug build is not working.

Error message (partial)
Check dependencies
Code Sign error: No matching provisioning profiles found: No provisioning profiles with a valid signing identity (i.e.certificate and private key pair) where found.
CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 8.2'

I reconfirmed that the private key and the privatization match for the same symptom, and it was reported that it was successful, but it has not been resolved yet.

In the description when generating a private key in MonacaIDE "The user name and email address must exactly match the iOS Dev Center registration information." However, if you register AppleDeveloper in Japanese and enter Japanese when generating a private key in MonacaIDE, you will receive an error of "Fail to create CSR."

Does MonacaIDE really need the user name and email address exactly match iOS Dev Center registration information?
If someone says that they can build even if they don't match, one cause would be crushed.

I contacted Apple Support to change my name to Japanese → English, but after waiting for 3 days, I didn't hear from them...
