Minecraft Marketplace Not Downloading

A few of my Minecraft Marketplace maps will not download and just say "downloading..." I cannot play these marketplace maps. When I open the Marketplace and look at the maps, a grey box replaces where the download button would be. I tried going into the Minecraft settings and deleting the world templates, but when I do this, I cannot re download them. Some affected titles are "One Block Challenge" and "Simburbia" These maps are permanently downloading, and it really stinks how I cannot play them, especially the ones that I have payed for. By the way, the maps are not just taking a long time to download, the have been like this for weeks.
