rooms on higher level wont work

[DanielJansen1995]

I first want to say I am a total newbie regarding revit, English is also not my first language so please try to explain things easily.

So I made a building with two levels in revit 2013, after reconsideration I found the levels too high so I changed them (from 4000mm per floor to 2600mm per floor). I did this by decreasing the size of the walls and dragging the  levels using the elevations view. After this I tried to create rooms on my higher floor which didnt work, the rooms on the lower floor did work though. 

I got this warning: None of the created elements are visible in Floor Plan: Higher level View. You may want to check the active view, its Parameters, and Visibility settings, as well as any Plan Regions and their settings.

but I really dont know what to look for

So the tags are not visible and in the table the area of the rooms on the higher level are all 0 m^2

It would be really cool if someone helped me because I have been struggling with this literally all day long and I have a deadline coming up

Thanks

for some reason I cant seem to edit my post for the second time, only wanted to say the area is defined in the table, the volume is 0 though

By chance, are the Rooms being stopped by a Floor element close to but above the Level with "Room Bounding" enabled?

You where right, my floor was really weird and a bit broken. Thank you so so much, you are the best 🙂
