The border of storm controller disappear

I’m testing the storm controller, and I used the basic storm controller just for testing.
I have two snapshot, and the previous works fine, the only thing I did was dragging the basic storm controller and change the init radius, then the next snapshot, the 3D member did some stuff with the map but not involving the storm controller, but the border of the storm controller just disappeared. I’m so confused because I try to modify the setting of the storm controller but it didn’t work. I also took comparasion of the two version, but the changes were some position of 3D models, add new 3D models, I can’t find what is wrong with the border of the storm controller
It would be very appreciate if anyone can gives some advices to me

the two snapshots DO both have the purple border line

the previous one has the blue border

the current one has no border, once you cross the field, it just damage the player
