Other issuers have other stunts, but managing to mess with the name in the original JMB account is not one I have heard before.
I got the JCB card VIEW CARD, so maybe they handle things a bit differently than MUFG. After I got my card issued, I logged into my JMB account only to see my registered name as MIDDLELAST FIRST.
