Lightroom presets rejected

Hello. I received a message that told me my file was rejected. But the explain is really simple and doesn’t tell me anything I can do correct the files. I made an effort to do this and I was very excited to offer a pack that I really use and made with love.

And I just receive a very simples message that doesn’t explain nothing and tell me that I can’t reupload.

What can I do to improve this material? It’s ok if I don’t sell, but I want to know what I can improve and made this more attractive and comercial.
