Ram Frame in-plane moment values

[Trob]

While using Ram Frame I notice strange in-plane moment values in my concrete or other-wall shear walls. When using section cuts I find that the moment fluctuates almost randomly with the height of the wall. I EXPECT to see a max moment at the base of the shear wall and a zero moment at the top, (cant. condition) or a max moment at the top and bottom (fixed fixed condition). Instead, I see the moment fluctuates from negative to positive in almost completely random locations. Can anyone explain this to me? Is there something I'm missing?
