After publishing why the players are joining in spectate and not spawning in the game

Fortnite creative map working fine and after publishing it works very fine the game is in public mode it starts fine for the party players but when another player is trying to join he will go only ro spectating while max players is 100 and only 3 are playing and its hoinable game

What setting the game should i take care to make the joining player join
Is there any special setting ?

There is an “Join in progress” option on island setting. Did you set it at Spawn ?
