Random Americas & Oceana starter edition?

So today I went to sign into the WoW companion app after a very long time, it said it couldn’t retreive data from device, so I cleared the cache and data to try and get on again, I got on, but it didnt load my characters (later realised i logged onto the Americas & Oceana region, not EU). I went onto the WoW armoury site and signed in, all my characters were there. So i went on my blizzard account, and it said I had a BFA account on EU, which was correct, but then a starter edition on Americas & Oceana. When i went to remove the starter edition, it said that starter edition was added 2 minutes before i signed into my WoW companion app. Now I know no one has been on my account as I have 2FA active so my phone would get a notifcation if anyone tried to get on my account.

Could the companion app of started the starter edition? As it was started around the time I tried to log into the companion app Americas & Oceana.
