I don't know, I played a couple of times, generated maps a couple of times, and in half of the cases, it only generated one two-way portal, and in a game with nikom, there wasn't even a teleport to the opponent's side... here, everything is clearly straightforward... I wouldn't really like to play with an underdeveloped template.
You definitely installed the game incorrectly. I have never had any problems with version 1.
