It shows i am on a team, but i am not

Hi, my issue is that in game on Americas server.

When i open the “Groups” tab, it shows that i am on a team called tag: 11111 name: AssassinNinja’a. (I’ve never joined this team and i don’t know anything about it).

I’ve tried creating a team to overwrite the issue but even being the owner of another team, whenever i open the Groups tab, it still shows that i am on this 11111 team. This is very annoying and i’ve had this issue on this account for years, but i am finally fed up with it.

Please help me solve it.

Thanks in advance.
