Graphic bug in line-up window

Hey guys,

my game seems to have a graphic bug/problem in the line-up graphics. Both in the tactics window and in the line-up screen before a match the players are only displayed as black squares with their jersey numbers on them instead of the regular graphic.

Here's a screenshot of the bug

I have facepacks, kits, 3d kits and logos (all downloaded from sortitoutsi) installed and apart from this everything works perfectly. I even deleted all the kits and reloaded the skin but the bug was still there. so it seems it has nothing to do with the downloaded kits.

anyone knows this bug? knows how to resolve it?
oh and I play on a mac if that helps.

cheers!
