I don't know how to reproduce this. I've never seen it before this map, which has deliveries moved and no prisoners. But as you can see, the filing cabinet took on the room requirements somehow, so that the room is showing a warning even though it meets all requirements.
Win7 32-bit, 4GB RAM, Core 2 Duo processor, ATI X1450 graphics card with legacy drivers (laptop).
EDIT: changed subject from "Items gaining room properties"
