LEAP Steel Load Case HL-93 vs HL-93 (Deflection per AASHTO)

I am looking for the difference between Load Case "HL-93" vs Load Case "HL-93 (Deflection per AASHTO)".  When running the reports, I see two parameters:  HL-93, and HL-93 (Deflection per AASHTO).  What is the program doing differently to these two cases?  The deflection results of each are drastically different.
