pole zero analysis validation using ac sweep

$

Hello ,i have built a circuit and ran a POLE ZERO simulation on it, after that i took  those poles and zeros and made a transfer function in MATLAB as shown bellow.

After that i  compared the MATLAB bode plot with AC sweep of the circuit . i get almost the same response however the peak at the AC sweep is much lower then the POLE ZERO transfer function bode plot.

where did i go wrong comparing them?
Thanks

p=[1.9128e-12+5.03292e9i;1.9128e-12-5.03292e9i]
z=[0+0i;-1.58e-21+0i]
k=1
[num,den]=zp2tf(z,p,k)
sys=tf(num,den)
bode(sys)
