Marketplace Maps won't update

So, lately I been having this problem were some of the maps I bought from the marketplace say update and when I go and try to update them nothing happens no matter how many times I click update. This is really annoying because now I can't play on the maps anymore because they just say update and I can't update them because the update button does nothing. I tried restarting Minecraft many times and even restarting my device and it still refuses to update
