Double of every player is being instantiated (when room count = 2 players instantiated = 4)

Here is the outline of my code:

1. Waits until enough players join
2. Once enough players have joined a countdown from 5 seconds starts
3. All players are joined into a new multiplayer scene

What is happening is that double the player count of players is being instantiated in the photon room. For example, if the room count is 2, then the players instantiated is 4. I checked, and there are no other GameObjects in edit or in play mode with this script attached.

Thanks!

Here is my code:
