I think I may have got to the bottom of my version of this issue. I did post else where so apologies for repeating myself if you read the other post but I wanted to add here in case anyone else came searching and found this thread.
I sold my M3 on 2022.20 i.e. BEFORE roaming profiles and profile based navigation was added and bought an MY on 2022.24 when then had been introduced.
I added home the way I had before i.e. once but crucially did not realise that I now need to add home to BOTH my wife's profile and mine separately.
As a result every time my wife drove the car, when she got home it did not know it was home since she did not have a home.
After a week or so I started to notice the incidence of sentry being on at home seemed to be mainly ( maybe exclusively) after she had been driving. I switched to her profile and no home set.
I imagine if your car updated to 2022.24 it would automatically add the existing home to all existing profiles but I switched cars at exactly the wrong time so it never happened for me.
I am guessing though that others are going to have the same issue in future, both new owners and existing owners who move house etc.
