When running the shear wall module, The snip below shows the reinforcement that RAM selected. with #6@9" and #4@12" OC and the section passes. But when I select another bar pattern with more area of steel, the moment capacity drops significantly? Then I reselect the steel bar pattern of #6 and #4 and then the original design does not work.
Are you using version 17.01.01.05 or something older? Do you have wall out-of-plane stiffness considered? I ask because this indicates a design at 90 degrees i.e. perpendicular to the wall major axis, which is kind of unusual.
I am using 17.01.01.05 and this is the Criteria used that resulted in these forces. I have tried removing and redoing the section cuts multiple times and if I consider out of plane I get similar problems. I have also changed my mesh to be 2 instead of 4 and that also did not work.
Send us the file then for review please.

Not sure what went wrong, but I keep getting an error with your upload, like it's an incomplete or corrupted file.
