Libraries that show up within the Library Tab (With the Graphics on the Left Hand Side) are made for the Free Player Version of Kontakt 5 which we do not support. For libraries that require the Full Retail Version of Kontakt 5(6), they will need to be loaded using the Files Tab or the Quick-load Browser.
