Player not always spawning in multiplayer game

Hello. I am making a simple multiplayer game and for some reason, all players do not always spawn in. I set my settings to “3” players and “play as listen server”. I also placed 4 player spawns. Is this all I need to do for spawning players in or what else am I missing?

I was able to fix this with the help of this video: UE4 Spawning In Multiplayer In Different Player Start - YouTube
