Yes: that’s the listing I went through. What you’d conclude from the documentation is that, at some point during the nomination process, the Government of Morocco made that claim. They’ve either since withdrawn the claim, or UNESCO has removed it. But, as with any false claim, once made it gets repeated, and the later repetition gets cited as evidence for the original claim (a form of circular citation, and one that historians get quite annoyed by because it’s usually quite a deliberate attempt to ‘hack’ the record).
