Can't search for players on some divisions

Hi, we don't have this league in FM under this name. Can we ask which league you are referring to in specifically? 

Do you perhaps have a custom database installed?

No Custom League Database, I just made a mistake copying the name. It's Campeonato de Portugal Prio (and group C, for instance). It's the 4th tier of Portuguese football.

Thanks for the info, we'll review further.
