Export to PDF - not grouping

Export to PDF - not grouping

I have a view which I am trying to export to PDF.  This view is set to group data by a certain field (room number), and also to sort data by date and time. 
 
When I export, the PDF file is only sorted by the date and time, room numbers are all over the place.  I would like the PDF file to look exactly like the table - showing the propper groups.
 
Admin:  Name of the view is "Tomorrow Schedule" - already shared.
 
Thank you.
