No need to shout.
If the section/elevation marker does not extend the full width of all the elements shown, it is asking you how you want to display the cut edge of that element.
From the Help Menu:
Boundary Contours
“Boundary Contours” refer to elements shown in the Section, Elevation or Interior Elevation window which extend beyond the horizontal limits of the Section (in other words, the entire element does not “fit” in the section window).
Use Boundary Contours in the Section Model Display Panel to define the display of this boundary.
Here, the left edge of the wall on the left does not fall within the section, and the displayed parts are shown as unfinished, without contours.
