Ventura "Find My" issue (wrong account) ?

[byke]

I have a security question.
And I know its a strange question, but I have no idea where to ask it.

I recently bought a second hand M1 Mac Mini, and it all looked good. Even though it was wiped, I rewiped it just in case, and installed Mac OS Ventura (Public Beta).

When I go into the Find my app on the desktop, I am seeing all my family and friends , devices etc.
(I use my iPhone as my main "Find me" device for sharing my location)

However, when it comes to "Me" on the Mac OS app, I am seeing that my usual icon profile pic is not there and a different icon with someone else's initials are in place (my initials are "MP").

I contacted Apple support and they didn't know what it was, and because this is a beta release, they cannot comment (officially).
I had them look over the serial number, and they could see that had previously been registered to someone else and the warranty had expired. And they could see that I was now the current signed in user.

Can anyone check if they have a public beta of Ventura, if a similar issue is happening to them ?
So that I can try and work out if its a Ventura issue at the moment.

Cheers

Update, I have now found that this abnormality changes based on disconnecting and reconnecting to wifi.

So I woke up this morning and the icon was missing and replaced with the initials "KD".
I then closed and reopened the app, no change.

I then closed the app again, turned off wifi.
Then turned on wifi and reopened the app and my correct profile image and reference to me was back in place.
