Comments field won't appear on CDJ 2000?

Ok...So I updated a usb stick on one occasion and miraculously got the "comments" field to appear on my CDJ 2000....And after re-formattimg the stick to re-do the process with a new iibrary, no matter which active or in-active sort/category I select in Rekordbox, I have never been able to see the "comments" category appear again on my CDJ2000's...

I use the Comments tag in itunes to store info for smart playlists in iTunes e.g. jackin, hit, weapon, deep, banger, new, vocal, female etc.....And I would like to be able to "smart search" if you will on my CDJ's in the same manner from USB stick.....

As I said...I did it once before...I can't remember if I imported directly from the bridge, or if I imported from a "collection" or "playlist" from Rekordbox...But whatever I did, I just can't repeat it...

What am I doing wrong?

Also I'm a bit confused as to the "category" tab with it's active and in-active options vs the "Sort" tab with it's active and in-active options....

Or maybe I'm not accessing correctly on the CDJ 2000?

Help please....
