@MuchMoreThanTees: The problem you are describing is sometimes a back end problem that you cannot do anything about, but it is also possible that a hard refresh of the browser page or a reboot may help if your cache is outdated or corrupted.
As an aside, @CoquetteBath makes an important point. You may want to discuss your business plan with a qualified intellectual property (IP) attorney. You need to include YOUR licensing information for all of the trademarked and copyrighted names and images in your shop in your listing, otherwise buyers (and Etsy) may conclude they are counterfeits. And a buyer could file a not as described case against you and both get their money back and keep the item.
The Mouse has been known to show up at an infringer's door with a court order to confiscate EVERYTHING that was used to create, manufacture, and or market the infringing items.
