dbo is making changes

Hi everyone,

We are in the process of updating and cleaning our records to conform to the recent Canadian anti-spam laws.  We are updating the e-marketing field of our constituents to reflect whether or not they have recently opted into our newsletter.  We make the change, save the changes, and then about a week later the file is reverted back to its previous state by dbo.  Has anyone else encountered this problem?  We need this information to save properly so that we can pull accurate lists.  How can I stop dbo from making these changes?

Thanks!
