I tested them ingame and they look good, but a lot of kits are not shown ingame.... like FC Zürich home, Zenit home etc etc etc
that is a IN GAME problem...it can be solved if you edit those kits before start a new game with the game editor(open editor, edit those teams, save that file, start a new game using that new file...you have to start a new game everytime you edit a team)...or if you have a in-game editor you can resolve that aswell (like FM oficial in-game editor or FMRTE)
the problem is that SI did'nt made some home work and for some team (if you look inside the editor) only have 1 shirt...is not a XML or kits problem.
