Domain Verification Issue

There seem to be a glitch, we upgraded to the Team Workplace, however after doing so it wasn’t what we needed so eventually each person in the team had to have their own account.

But when we reversed back we lost most of settings, including domain verification status, now when we try and verify domain it just doesn’t let us do it as it seem to think its connected to an acocunt.

Really need help. For reference our domain is softwarehouse.au

A domain can only be associated with a single account, so you cannot have the same verified domain for each of your accounts.
