Club customizing error

Same here. I have figured out what my issue is. My club recently unlocked the Pennsylvania logo with the Liberty Bell on top. The error seems to happen when I try to adjust the colors of the logo but only for our alternate uniforms. I took it off and put the old logo on and it's fine. Tried the Pennsylvania logo again without adjusting the colors and it saves but I once again tried to change the colors and I get the error. It could be a logo you are using. I am also getting this error now when trying to adjust my clubs strategies.
