Projectkorra error

ProjectKorra commands sends me outputs that they work but their job isn't done "I do /b b (element) and it gives me an output that it bonded it to my inventory but in fact it isn't bonded" so I went to check in the abilities folder, and found it empty when it should have files, I even installed the folder from the main websties and checked, but sadly I can't add that file to the server myself, aternos must add it, so please fix it or tell me is that an error from me
