Error creating playlist (right clicked all Crash Bandicoot games after searching for this in my entire collection) and right click ADD TO PLAYLIST..

and made the playlist, assigned it the platform I have created where all my playlists go (Mixed collection), and then also set filter to auto add any game with SERIES "containing": Crash Bandicoot, clicked OKAY, found the list under mixed collections, showing 7 games, clicked on it, an then error appears. LB stays open, playlist seems fine..
