When you contribute a change to an existing profile you must give sources for the changes, for the change from Single- to Dual-Layer that might be a "verified with Nero Info Tool" or any other tool that provides the needed data.
Another MUST for the contribution notes is the reason for the change, so in case of the incorrect existing scans you should have written something like "corrected scans with correct UPC. Source for this change: Own DVD"

There's no way to manually clear out your contribution record, entries are deleted automatically after 30 days.

If you command extraction of Disc Info with DVDp doesn't it capture the Dual/Single layer status for DVDs?  I know it does for HD & BD discs.  No external tool required.

I found this to be iffy at best. There has been times when the DL checkbox was checked automatically... but also times when it hasn't automatically been checked but when I would double check the info it was actually a DL disc.

Someone added this title,but the UPC code does not match up to mine

Titles are released all the time with differing UPC codes. If your UPC is not in the database (although your "title" is), you need to submit a new profile.
