Two Hass.io Administrators

At some point I inherited two Hass.io administrators:

The cannot be renamed or deleted or changed in any way via the web UI. Via looking through logs, I have reason to believe having these two users is messing with/crashing when accessing auth on some of my Hass.io add-ons.

Has anyone else ever seen these duplicate users? What could I do to remove one of these users?

Thanks for any and all clues in this matter.
