That seems to agree with the code I dumped and examined. It doesn't include the new code (9147430). I'm guessing you got the wrong link, i.e. the one you posted to your Store code.
It would be struggle to try and tease the two married codesets apart. Is that a marriage made in eBay Hell or what? OK....I'm laughing too. Probably best to just cancel that listing.
My best advise is to use of the existing broken listings with no background and try to add that code merely for test with PREVIEW. You don't need to save, just test for good result. If that seems to restore the background correctly, we can go from there. I realize you have different backgrounds for the different Store groups, so we'd need to make a code fix for each separate group/background.
