Webench LM3401 design has wrong MOSFET symbol

Hello:  I just shared a design with Howard Chen and Eric Hackett.  Customer reports that the design works OK but the FET symbol is Nch when it should be Pch.  

Also, cannot optimize design "optimixation data not available for this design'  what exactly does that mean and why is that happening?  When can we or can't optimize?  

EAU 80k/yr, thanks.
