Can't sign greyed out players

[CyanideandJD]

This doesn't happen in every save but has happened in enough that it's kind of annoying. The option to offer a contract isn't there. I've tried changing staff responsibilities to see if that helped but no luck. The transfer window is still open so it's not because of that.

Grayed-out players are not available. Maybe it's because you didn't add those leagues/zones in the playable ones. Really depends.
