Uploaded - my Editor Created Club Newark (light blue) play Leicester in next match in save- 

Newarkblue vs leicester away.fm

is file name. Leiecester will proceed to play in away kit pale/turquoise against a white/blue kit combo. Previous fixtures show Brighton as another annoyance with same issue. Oddly though, Chelsea (Darker blue) triggers away kit switches.

I've played with created club in pale blue and seeing similar with all Blue/Blue Clashes. Not sure if related but then number colours tend to mis-match with these same teams. Let me know if you want a match file or save.
