Issue assigning props to an editable creative_prop reference in custom devices

Hi, I’ve been having some odd issues assigning props to exposed creative_prop references. I was adding basic Fortnite floor tiles to my devices this way, and it was working fine, but I’ve now found I sometimes can’t add new props to these references. Oddly previous references still exist, but if I clear them and try and re-add the exact same prop, it won’t let me. And I can reference some floor tiles, with no obvious difference between allowed and not allowed. What could interfere with this?
