Are you sure it isn't because it gives the option for the single column version:

Box Name: hints_manager.php
Left/Right Column Status: ON
Location: (Single Column ignores this setting) RIGHT
Left/Right Column Sort Order: 205
Single Column Sort Order: 0
Single Column Status: OFF

since the single column is "off" it shows one as commented out?

I am making a total guess. Like I said I just copy, paste, and upload, lol.

Thanks,
