can't update template worlds

I am not able to update my Minecraft market place worlds I have tried un-installing the template world  but nothing seems to work! 😡 This is preventing me from playing my favorite mini-games and adventure maps! I can't provide screen shots because you cant see it in a screen shot only a vid but it says it can update then it opens the download screen and when i click it it closes the download window and brings me back to the screen that has the world and an update button click it same thing happens.
