Just tried to contribute a title that's already been submitted and approved as a test. It says the UPC is invalid, even though it definitely isn't.

Contact R2 UK 7321900150415.

Is it still using the old contribution checking and expecting a 12 digit UPC for existing profiles?

Edit

It does show a second listing in my contribtuions, but if I look at the notes page there is not a second contribution there.
