There is an error in the way the section calculation is done that prevented finding a solution to the intersection of the section plane with all the surfaces. In some numerical solutions this is unacceptable, but for section calculations the cost of avoiding failure by adding more verification checks to the calculations would result in unacceptable increases in calculation time or memory usage. As a result, particularly when a section passes through a plane the geometry was created on or is clocked-to, there is a small chance that no intersection will be found.
The general way to avoid this is to move the section plane a small amount from the creation plane. Even .005mm can be enough to get a visually correct result.
