I have found that Logos don't stay if you go back into the uniform editor for seemingly any reason. Want to change the color of your socks? Be prepared to reload you logo on every hat, helmet and uniform.
If you go into team details at any point after creating your uniforms (which does include your logos) it will reset it right now. Until SDS fixes this you will probably wanna avoid team details unless you're changing information about your team's name. location or colors
