I had a look through our bugtracker but I couldn't find the specific scenario you describe.
It may be a bug; would it be possible for you to send over both the create script for the table from the DB, along with the files relating to the same table from the Tables and Data folders in your scripts? I'd like to see if I get the same behaviour here, and if so, log a bug.
If you can send it to email@example.com
with F0065780 in the subject line, it would be great, thanks.
