I have a project with a number of drawing sheets.  Right now it's a number of rack and pictorial sheets for 3 sets of rooms.

On some sheets I can select all.  In the attributes window the attributes are shown and can be edited.
On other sheets when I select all, the attributes window is completely empty.
What I'm trying to accomplish is to set the location for all the items on a sheet to the same thing.
For example, I'd like to set the location for everything on sheet A to Hall A.  Set the location for everything on sheet B to Hall B.

The issue doesn't seem to be associated with a particular module.  One rack sheet will work as expected, another rack sheet will not.  Same for pictorial sheets.

Is there something I'm missing?
