That isn't how it is supposed to work so that is frustrating. If you continue to see this, please go to answers.microsoft.com so they can help you troubleshoot.
If you are an admin, you can remove them from AD, too - instructions for doing that here: https://www.wavecoreit.com/blog/teams/removing-microsoft-teams-guess-access-user-team-part-2/
