How to make spawn selection independent of the player (Warcraft 3)

I have that the white color should be, for example, at the first point. At the same time, there are 6 such points on the map, and each has its own color (Blue there, red there). But when I want to play on the white color, I am thrown to the red dot, and the white is occupied by the AI. I think it's because red is shown as Player 1 and I play solo and I'm always that Player 1. How do I make sure that whatever color you choose is where you spawn? Maybe I'm just a beginner, and this is an easy problem, but help, if not difficult)
