Hey guys, I know this is not a support website but I am having an issue with loading shelf icons (Scripts) onto a few artists Maya shelves. I am placing the Shelf.mel in their 'C:\Users\Artist\Documents\maya\2016\prefs\shelves ' and the shelf itself loads into Maya, but it's not creating the icons, and I am able to call the commands from the script editor so I know it's not an issue with the code.

Has anyone experienced this? or have any idea of what I should do? I have already deleted their userPrefs.mel and tried a few other things to no luck. It's also happening on random machines, with the exact same systems. They can't even create and save their own shelves.
