Can't update worlds bought on market place

I have a few maps and one that I just purchased on the market place that says I need to update. I go to update it it will say update complete but the button never changes to create. It just says update. If I try it again nothing happens. I have tried to correct the problem with help on the Minecraft site but nothing seemed to help. Tried us8 g my hotspot on my phone tried uninstalling and reinstalling Minecraft but nothing changed. It seems to be stuck on update even after it said it has updated.
