Multiple profile pics? Wrong profile pics

Something very strange is happening with my Apple ID.

I noticed that on my iPhone, the profile pic that is showing for me is not my profile pic. It is actually my wife's profile pic.

On my Apple watch, I see her profile pic there too.

When I check the System preference on my *iMac,* there is no profile pic showing (I get the default, no pic chosen image)

OK, so over to my laptop ... when opening System Preferences, I see a different profile pic. And then when I click on Apple ID, there is yet *another* profile pic.

What the HECK is going on? How is it that if I set a new profile pic, it is not updating across the board?

Oh, and one final thing ... when I checked activity App on my Apple Watch the other day, it showed *my wife's first name* on a message.

So, this is not just a case of me being precious about the profile pic, but more a question about why I am seeing her details on *my* devices.

The pic below should demonstrate this.
