Error in Design - Simple Steel Flat Truss

Hello All,

I have modeled a simple steel truss to check my hand calculations.  When viewing the global status of the model, the diagonal members are shown to have "Errors in Design."

The members all have ratios from 1.84 to 3.6.

However, my hand calculations indicate that the members have much higher capacity than the demand.

My question:  How can I find out what AISC design equation is used by RAM Elements so that I can look into the issue further?

I am using RAM Elements Connect Edition Standalone 16.2.0 on Windows 10
