This is only when a player who was in a game REJOINS the same game. Which is common for maps that dont have a lot of players. I here what @AtAshTag is saying, and I have never seen an issue before when using the SpawnedEvent from Player Spawner. I use Player Spawner for my player adds. Player Spawner occurs after PlaySpace.AddedEvent. The island I am seeing this on was introduced before 36.00 and I tested join in progress a lot and it was a lot of rejoins and I NEVER saw an issue. As I said earlier I was able to see an issue on 3 of 6 rejoin attempts.
