Why in standalone the number of controllers is greater than in elditor?

I’m checking this inside a timer to make sure it doesn’t vary.

In the editor the number of controllers is equal to the number of PlayerStates in the GameState array.

However, in standalone, the number of controllers in the world is equal to the number of PlayerStates in the GameState array plus one.

This is normal? Which is the reason?

Thank you so much!!
