Shell/thin section not showing in mesh

Hello - I have made a sheet metal part (strut of a scissor car jack) to analyze in an FEA static study. When the meshing occurs, both sides of the strut should be orange to represent the shell characteristics. However, one side appears as grey (solid mesh) and the other appears as orange (shell mesh). Any ideas on why the strut isn't fully orange would be so appreciated!
