Ok, that means that your table does not use the same structure as the table for the CMS preset.
so to use the CMS Preset with your own table, open the manage pages tab, end edit each of the pages to reset the columns that will be added.
In reality, the presets are not intended to be used with your own tables, they are set up for a specific table structure.
when using your own table, you should use the new From blank preset and then set up the pages option on the manage pages tab. after creating the settings, you can save your own preset to be used with that table structure.
