I-Tunes Smart playlists disappeared in Rekodbox

I am using a pc laptop & I am using Itunes to manage my music library. Everything was working perfectly fine & from one day to the other my Itunes smart playlists stopped showing up in Rekordbox. If I click on the itunes and then go to all tracks all of my music does show up in Rekodbox & I am able to play the tracks but my smart playlists are no longer showing up.
