I do not see this (using fairly random table
creations since you didn't provide the schema)
in 7.2devel.  I get 7 and 7 at the end.  Which
7.1 are you using?  Have you tried upgrading
to 7.1.2?

In any case, a script to create the tables and 
views and populate them with the appropriate data 
would be helpful here since it could be dependant
on the actual table structure.
