why I am getting a cut bode plot of peak current mode control of buck converter (demos)?

hello everyones,

I am trying to get the frequency response of the demos given Buck Converter with Peak Current Control and using as reference the Buck Converter with AC Sweep Analysis. however I am getting weir result as you can see in teh attached file. I am not getting all the gain value and phase value of all frequencies which means I miss something in using the AC sweep block.

any help is welcome
