verify database should update the schema

if you have a production and development server make sure you made the changes/updates in both locations and/or the report is pointing to the correct server.

Is the report table using an alias (overridden table name)?

The 3 areas I can think of are what we covered.
The databse needs to be refreshed
The odbc points to the wrong db server
The report is using overridden tables so you need to change the view in use not the view that it looks like it is using.
Now I have sworn all 3 of those are correct and spent hours looking at the view and the report and eventually figured out either option 2 or 3 was not correct and then fixed it in one minute.
Sorry but these are the only culprits I can think of for the scenario you described.
