I'm trying to add a bunch of third party libraries and am doing so with Kontakt 5.6.0. Some libraries add fine but others don't appear in the libraries tab, then when I try re-add the library I get the message:

'Library X' already exists within the Kontakt Libraries tab

When I close and open Kontakt and try add it again it lets me add it again, but again it doesn't appear in the libraries tab, and then when I try add it again I get the message above.

Any ideas?

I'm using Kontakt within Ableton on Mac
