Surface Classification Unknown Concern

Good morning all.
In my project, I have FG, OG,SG, Defined via tracing the cross sections. Then I added the site marker for asphalt and the surface "FD with subgrades adjustment " was created. Yet when I look at the surface nothing is shown and trying to do a earthwork report. I get the following error “The Surface does not define a valid area.”
Thank you.
Jason.
