So League management on PS4 does not give the option to remove people or inactive players from the League. Looks like it is only a PS4 issue, I just updated DCUO on my PS3 and tried it and it works fine on PS3. So Clearly it is only a PS4 issue. Hopefully they get a fix for it soon. PS3 has Promote, Demote, Remove From League PS4 has Promote, Demote, Leave League "which will remove yourself"
