Yes, I have used data assist many times to create a full set of pages creating the pages to use certain columns as menus and not been able to reproduce the problem.
The columns that are included in the select statement created by data assist are the columns you select to display for that page.
Only if you remove the column form the page in the wizard will the recordset be created with it that column in the select statement.
There is some setting you are changing while running the wizard that is causing the issue.
Perhaps if you could take a screen capture of each page of the wizard, this will help see where the problem is coming from.
