converting CPWG/ CPW (coplanar waveguide in ADS) to gerber

Hi! Greetings!

I am used to generate mictrostrip to layout and then export to gerber in ADS.
However, I am first time dealing with CPWG lines. I can see CPWG converted in the layout with center conductor (line width W) and thin ground lines at distance (Gap=G) apart.
I can see the same once I export the layout to gerber.

However my doubt is why the outer ground lines are so thin and not the typical PCB layout lines where we have center conductor and a gap, and a ground everywhere else (the way it should look like as shown in the attached image "Expected").?

Please guide me in this regard.
