This might be a long shot, but did you use the content center to create that channel? If so, it might not be sectioning the channel because it is a "standard" part. Depending on your document settings and / or drawing view standards, standard parts may not automatically participate in section views.
If this is the case, no hatching would show up. Try editing the drawing view > Display Options tab > Section Standard Parts > change to "Always". If what I described above is true, then you will suddenly have hatching in your view.
