Use online mode.

im using this on bungee my prison has to be offline mode

Enable ip-forwarding in Bungee's configuration and bungeecord in spigot's configuration. Consider reading the wiki before setting up your server.

ip-forwarding in the bungee config is set to true and bungeecord is set to true in the spigot.yml and inside the server properties online mode is set to false
i don't need to read the wiki as i have already set it up correctly.

5890cbd1-e2ff-3cc8-a44a-d3acc1d24714 this one i looked up on namemc and does show anything so this must be the fake one and this one 008027a2-26df-44c7-89b4-2c4f4fd71b07 i looked up and it shown the correct person. plus im not the only one whos had this issue

This isn't an issue that's possible with online mode. There is something wrong with your setup.

If it was set up and firewalled correctly, you wouldn't have the issue. Are you sure the UUIDs are proper online-mode UUIDs in userdata?
