Remote tab doesn't list my repos (only of one account)

I've three different accounts activated in SourceTree. Two different Bitbucket accounts and one GitHub account.

If I switch to the Remote tab in the SourceTree overview, I'll get all repos of my private Bitbucket account and of the GitHub account. I don't see the repos of the Bitbucket account of my company. I'm not an administrator, but I've rights to read and write. In the browser I've access to all the repos.
