Well here's a hint for those who messed it up like me.
lost all my room tags and they were placed and were in the room schedule, so I knew they were somewhere
but my floor plan did not show them - all other tags were showing
Visibility Graphics VG showed everything ticked
view ranges, range views all fine
reveal hidden views showed nothing
I had placed a ceiling and therefore selected all and picked the ceiling and hid it - but that did NOT change anything.
turns out I placed a ceiling in floor plan view and it went in at floor plan view and therefore covered the floor.
The ceiling was showing on hidden elements as green but that meant it was still covering the room tags
its seems that even if you hide a ceiling that is on the floor it will still hide the room tags
revealing hidden elements will not show up what is under the ceiling
slightly embarrassing but it might help someone else
