Legal Shiny PKHex Pokemon Won't Transfer?

[Pokefnn]

I caught a Xerneas and edited it's IV's and nature on PKHex to my liking, and I even copied it and traded the copy through Wonder Trade to make sure it was legal. That worked without any problems. However, when i make it shiny it appears to no longer be legal as it won't go through Wonder Trade; i keep getting the message "We could not find a trade partner for you...", but as soon as i try with another pokemon it works. I've uploaded the file, could someone please take a look at it and tell me what I'm doing wrong?

For some reason the "manage attachments" button isn't working for me, so i uploaded it to tinyupload.
