Ah, yeah, that sort of slipped by me, apologies for that...
You somehow have two accounts with the same display name. As my colleague noted, the display name must be unique (as must be the email address).
It's possible the 3rd-party SSO was the indirect cause of this, but you need to change one of those account's display names to something unique, in both the ACP and the Wordpress admin panel. (From what you've said so far, I suspect you'll be changing the "Member" account and not the "Founder" account.)
Once that has been changed so there is only one account with that display name (John Hatcher), check to see if the problem still happens, and let us know if it does.
