diodes - Why current appears at reverse bias?

I am simulating time-domain graphs of a Schottky diode model.

I am expecting ~zero current at the negative half cycle. But I am seeing negative current. It's only about 3mA, but based on I-V curve, it is about 0. Does anyone have an idea what might go wrong?

diode model:(from datasheet) Is=30e15 Rs=8 N=1.05 Tg=1e-9 Cjo=0.1e-12 Vj=1 M=0.5 Fc=0.95 BV=5 IBV=1e-5 Eg=0.69

Answer

At that frequency you have this...
