I don't know if anyone else has the same problem with me. I can import any kits by using EAGraph but not Dutch league teams. So far I only managed to import kits for Feyenord but not any other teams for the league. Can someone enlighten me please?

Maybe you customised the teams with the correct names. So what you have to do is to customise back and find the right jersey. I've no problems with the Dutch league teams.

Or another step you reload the previous names and then you'll get back the jerseys in order.
