There is a new version forthcoming where we addressed a number of issues in Concrete Wall design. I saw one case like this which was resolved simply by deleting and recreating the section cut. If that does not work in your version, send over your file and I can check the latest. Secure File Upload

Seth, I understand the difference between the major and minor axis bending. The issue here is that the program is taking the major axis moment (in this example 1803.49 kip-ft) and for the same section cut of the same design wall group, happens to randomly apply this value as a major moment, or if I delete reinforcing and reapply, will apply this same moment as a minor moment.

Right, 0 or 180 degrees is pure major axis bending, 90 or 270 is pure minor axis (out of plane bending) which have different capacities for rectangular cross section.

As a follow up, it appears as if scenario 1 Mu = Mmajor, whereas in scenario 2, Mu = Mminor.
