Good news, you are not doing anything wrong.
For some reason this file get corrupted and the datas for your projector are now empty.
I created again the file, and I include it with this post.
You just have to transfert it to your Cuety, and you will have a new LEDj entry at the top of the manufacturer list where you will find your fixture.
Sorry about that,
Enjoy

I updated the file to merge it with your previous fixtures!
