I am trying to promote my Diablo application mileage (Car Mileage Calculator). In the packages interface it says

"Section: user/other
Warning: This package is not using one of the allowed user/* sections!"

I assume this is why the promote button does not appear. I have changed my Section to user/utilities but I still get the same warning as above for user/other even though I have changed the section in extras-devel. I have examined the .changes file and the File section does have
user/utilities.

Can someone please help me figure this out. I am stumped. It must be a problem with the packages interface.
