TPS54528 Bode Plot using switcherpro

Hi mates,

When I ran TPS54528 swticherpro simulation, it got some problems about the bode plot.

Spec: Vin=12V, Vout=3.3V, Iout,max=4A

Schematic

Is it the right result? 

If yes, why bode plot can not be measured through switcherpro? Does it relate to TPS54528's control topology, DCAP2?

Thanks

Grace
