Existing Cross Section Shoulder Shape Filled In

Hello,

I am working in OpenRoads Designer 2022 and am creating existing pavement boxes using a corridor. In the corridor file, I am using the standard template with 5 points (left shoulder, left edge, center, right edge, and right shoulder) that follow the surface at a specific depth. I then use point controls to tell each point where to be. When this is done I opened a cross section file and referenced in this corridor file. I cut the cross sections and the shoulders are filled in gray. When clicking on the filled in boxes, there is no option for fill. There is nothing in front of the section because if I turn off the reference display for the corridor, the entire pavement box including the filled in shoulders disappears. I am not sure what is causing these shoulders to fill themselves in. Printing still shows these filled in. Any thoughts on why this is happening?
