Until someone pipes in - in my situation (three call signs registered), the only success I had was by changing them individually from the main registration screen on
http://www.eqsl.cc/qslcard/Index.cfm and not via the
My Accounts within eQSL. Now, it may have just been me - but, that was the only way I successfully changed them. You might change it in one place and see if it works across your call signs and let us know. I just didn't have any success that way.
