Why won't it let me submit my uniforms

So I was updating a uniform to be more true to real life so I added a couple things to the jerseys and stadium. After i did this i went to submit and it said there was something wrong with my socks so I changes the under color hoping it would fix then it said my pants which have nothing on them so i changed the brand logo color then it moved to my helemt. I feel like theres nothign wrong and it's just bugging out.
