Utility Ratio based on Parameter

Hello,

I am performing STADD analysis on V22.08.00.175 for one of Tech structure as per IS 800 code and defined two envelopes with Strength and Serviceability load cases and accordingly defined two different Parameter check with Code check i.e one for (parameter 1) strength check and other for (parameter 2) Service check. However, it seems that STADD is only considering the Parameter 2 ( which is Serviceability case)  for showing the Utility ratio and not considering the stringent Case among Parameter 1 and Parameter 2 and then providing the Utility Ratio.

Could you please advise if this is Bug in STADD or is there any other suitable method to perform the check and get stringent result.
