This page, as the Apostolic Constitutions of PBXVI and St. John Paul II did until recently, links to a non-existent Spanish product. It should link here.
I suspect, especially given similarities in product ID numbers, that this is a systematic error caused by whoever changed the product IDs of various magisterial Spanish resources forgetting to update the relevant links. Perhaps fixing these links as a class may help all of the Spanish magisterial resources stuck at 0% in Pre-Pub. Or maybe that's another bug?
