Console Sharing Question

I bought my son the ultimate addition for his PS5 today, when I log into my own login on HIS PS5 I can access and play the game.
However when I go onto MY PS5 to go and play it it’s not transferred across, despite being able to play it on my login on his PS5.

Is there any way around this at all? Console sharing is enabled.

He’s an ultimate team player and I’m a career mode player so I’m not interested in the other benefits the ultimate edition comes with. 
Any help would be appreciated!
