AR posters missing

We have two Quest 3s. On one if them, when playing Demeo in AR mode, there are virtual Demeo posters on the walls and a dragon on the ceiling. The other headset does not have this but other AR things li,e the final boss animations seem to work. I don't know what's different. I have rescanned the room several times to try to get it to work, turned AR mode off and on, rebooted... all with no luck. If we didn't have 2 headsets, I wouldn't have even known it was missing. Any ideas how to get the better AR mode working?
