multiple profiles on one Microsoft account on Teams

I have two profiles for the same Microsoft Account when I access Teams - one syncs to my emails and calendar, the other doesn't.  On my mobile device it gives me a choice after I log in. On my desktop it redirects me to my 'other' account after I sign in to Teams (sadly the wrong profile otherwise I wouldn't be concerned)!  Can anyone please tell me how to remove the second profile on Teams bearing in mind it requires the same email address to log in?  Many thanks.
