AISC Code Check

Hello, I am new to STAAD and have ran into an issue when checking a model. The model was initially checking for ACI 360-10 so I went to the STAAD Editor and changed the code check command to 2016. This changed the utilization ratio drastically on most of the channels in the design, but it did not effect most of the other sections. In the steel design tab on the critical beam (Beam 20), STAAD shows that the Utilization Ratio went from 0.979 (2010) to 0.65 (2016) changing the critical Code from H1-1b to F2.2.

I am using STAAD CONNECT Edition V22 Update 4

If you have any advice or help that would be greatly appreciated. Thank you!
