MAYA_SHELF_PATH not working, empty Maya shelves
Custom Maya shelves icons not loading, maya shelf bug, Maya not loading shelf buttons - 04/2017 - #Maya

You set MAYA_SHELF_PATH in Maya.env but shelves are not loading, or icons don't display.
Maya requires MAYA_SHELF_PATH to be the very first variable defined, so you should check that.
You can also add to your system environment variables MAYA_SHELF_PATH.
