Now ranked bronze 5 in team play despite not being on a team

I have not been on any ranked teams this season. Apparently merely being invited to a ranked team is enough to give you their ranking? I'm now sitting at bronze 5 despite not being part of the team that's ranked at bronze 5

This bug is ridiculous. How do I get a ranking from a team I'm not even part of? This needs to be fixed ASAP

edit: declining the invite and relogging removes the "bronze 5" team 3v3 ranking from my profile, but I'm not convinced it's truly gone. And even if it is, this bug is completely ridiculous and needs to be fixed.
