Hi, i changed the name of my world thinking this would simply change the name however, i seem to have lost all of my data meaning my new world is entirely clear. any help on how to restore this data would be great thanks.

Changing the level name on the panel doesn't change the name of your world. It changes the default world of the server. And since you changed that to a name of a world that is not on the server, it created a new world and teleported there. And playerdata is saved in the default world and since that got changed, your inventory got reset. Do /worlds and teleport to one of the other worlds to get your stuff back. And just change the level name back to what it was. And you will just have to give yourself your items back using creative.
