Smart Playlists Using "Most Often Played" as a Parameter Not Working

Have created a Smart Playlist entitled "Most Played". I do a "Match All" to exclude certain genre's (Genre Does Not Contain Children's, Genre Does Not Contain Christmas) to focus on Rock, R&B, etc. I "Limit To" 100 items, "Selected By" "Most Often Played". I attempted to introduce another exclusion, which is a particular playlist (regular, not smart) created for my children (Playlist Does Not Contain Children's Favorites). When adding this playlist to the exclusions above, the playlist is repopulated but ignores the "Most Often Played" selection. The "Most Often Played" selection is ignored anytime i reference another Playlist within a Playlist.
