When this mod is downloaded the item description name appears twice when the item is on the ground and looked at with world tooltips.

Hit the key to open the tooltips config. Number pad - by default. And go ahead and check the option to hide the mod name. That will fix your double up.

Thanks for letting me know and I'll get a version where it auto disables.

Thanks
