Having issue with "It's a Trap"

Just started recently but imagine the Trap is a Square with 4 sides.

Let's call each side as is: East, West, North, South.

Now when I set my trap up and place it in the GM layer and test it with a PC Token the following issues occur.

1) The PC Token is walking North of the Trap and avoids it - Trap isn't Triggered - Working as Intended
2) The PC Token is walking East of the Trap and avoids it - Trap isn't Triggered - Working as Intended
3) The PC Token is walking West of the Trap and avoids it - Trap isn't Triggered - Working as Intended
4) The PC Token is walking South of the Trap and avoids it - Trap IS Triggered - Not Working as Intended

I have checked Dynamic Lighting to "BOX IN" the trap so it can not view things outside of it - It still triggers the trap if the player walks south of it.

If the Map Size is 10x100 and I placed the trap on the 5th and 6th column of the first 2 rows and have a Token PC walk on the 5th & 6th column of the 77th & 78th row, it still triggers it. Doesn't matter how big the map is, the "2x2 trap" acts like a 2xInifinite, regardless of Walls in the Dynamic Lighting layer.

Not sure what to do.
