Code Set - Sample Line Issue

[DBill2508]

In this file, Cross Sections, the Design drawing (Corridor, Vertical, Surfaces) is X'refd into the drawing. Alignment is then data ref'd, sample lines produced and section views created. Upon review of my cross sections I noticed that some of my ditch elevations were not being labeled, through the code set style. These two sections (Sections.jpg) are utilizing the same assembly within the same corridor. When I view the "Corridor Section Properties" of each of these sections they show different results in the "Codes" (Image 1 & 2).

Notice that the one ending in (451) does not contain any of the point codes associated with my subassembly but the other section (457) does contain all of the point codes. I have reviewed my corridor, redone my sample lines and recreated the file with the same results. Has anyone ever seen this or know how to add these codes into the specific section view?

Thanks for any help.
