Problem Description

Note: This issue has been resolved in the updated version, v17.02.00.130 Installing this version should prevent the problem.

* The exact version where the issue started is unknown, but it may go back as far as version 17.00.00.49.

When a designed and saved model is re-opened, the program recalculates the beta angle of the resultant horizontal section cut forces. These global forces were not converted to the local axes of the wall prior to the calculation of the beta angle.
Effect: An incorrect beta angle was calculated and displayed for the resultant forces on walls at any orientation other than 0 degrees. Generally, this was only a display error. However, subsequent optimizations may have been based on calculations using this erroneous beta angle, resulting in incorrect designs. 

Here is an example of a skewed wall with major and minor axis moments. The beta angle below are the initial values used, based on the local axis of the section. Note that the angles are about 30 degree off the 0 or 180 degree axis:

When the same wall is reviewed in s later session without performing analysis the values are off: 

Solution

Update to version 17.02.00.130.

Where that is not possible, only use or print the results from Concrete Shear Wall Design immediately after running Ram Frame analysis.
