Issues adding a minecraft map

Hey guys so just discovered this tool, trying to add some custom maps to minecraft but haven’t had much luck. The first map I added went fine but everyone since then either freezes my xbox or gives me an error message that it cannot be opened. Any tips would be greatly appreciated.

So far these are the two methods I’ve used

  1. Move profile to usb
  2. Put usb into pc and insert map, then rehash it
  3. put usb in xbox and either move map to hdd or boot it off usb

second method as recommend to help my issue

  1. Make new minecraft map and save it to usb
  2. Move usb to pc and right click on the contents and replace with new map
  3. Rehash it
  4. Boot it on xbox.
