my e-mail address not removed from a group I left/commits show up under wrong author.

I set up a team. The e-mail I associated with that group is my own. After a while of owning that group I gave it to someone else. But, that did not remove my e-mail address from the group.

Now when I log in under my e-mail, the website shows me https://bitbucket.org/account/user/coventsystems/team_disabled/?next=/account/dispatch/ ...

which tells me I can't log as a team member anymore, but I have to log in as the group's owner (the new owner). Obviously that's not possible.

How can I get my e-mail removed from the team's account so I can reassociate it with my own?

Thanks.
