To edit the host player, you need to edit the Player tag found in World Settings. The host player file goes unused by the game. The UME works fine. Items and edits do not always transfer over from Windows 10 edition to Java edition, so whatever you're trying will likely not function how you want it to. For future support requests about the UME, please contact me directly through my website https://www.mcmodtool.com
