Wood Gateway/Gate Placement BUG or Game Design ?

I can place the gateway right next to the metal mouse but I can’t place it’s gate, it snaps to grid but it’s still red.

Is it the same for wood structures?

My plan was to place a gateway right in front of the metal door which didn’t work out because I couldn’t place the actual gate.

Is there like a minimum distance it must have between itself and other structures?

If yes I don’t see the point allowing to place the gateway itself, it’s just a waste of resources since you can’t place the actual gate.

So, same thing happens if you want to place ti near wood foundations/buildings??
