Hello Jason and Nazmul Jaq, RAM Connection supports different design codes that have specifications that have changed in newer versions, the free edge buckling is only included in AISC 360-05 (AISC 341-05) where it was included and it is NOT included for AISC 360-10 (AISC 341-10) nor AISC 360-16 (AISC 341-16) due to reasons Jason detailed, if you switch the code from AISC 360-05 to AISC 360-10 or AISC 360-16 the warning will not be reported.

Excellent. I knew I hadn't seen it come up in quite a while on any of our projects, so it surprised me to see the topic again after all this time. Thanks, Carlos!

Can you please upload the file here? It seems from the warning the gusset plates needs some additional check which program is not performing and user needs to take care of that. It will be easier for us to comment better once we see the model.

We check the equations pasted below from the Seismic Design Manual p3-63. The first edition of the manual corresponds to the AISC 341-05. 
 
 The gusset plate stiffeners are not provided by the program and the user needs to take care of it manually.
