Item leveller not working

This is happening for me with both the F2 option and the automatic mouse option. I am unable to understand the cause of this and would like to know if anyone else is having these problems. Might be the new DLC update. Anyways, would appreciate some help and if possible a link back to the mod to download the latest version. Please tell me what to do. Thanks!

Why don't you use the save editor? You can level all your items with it. Open your save, go in the Backpack tab, press the sync all button. Done.
