Kits are not automatically created. CM16 can not automatically update the quads by itself, but you can go in-game and download the latest squads, then exit and start CM16. There's a menu option to update the squads using the squads files located in "My Documents\FIFA 16\..." When you have discovered a solution, it would be kind to share it so that it is visible to others with the same problem. Neither CM16 or FIFA 16 existed when CM15 was created. So naturally my guess would be that it can't work automatically within CM itself - you'd have to do edits manually.
