AC simulation plots frequency decade lower

[Garry Grut]

This schematic expects the freq. for Vout_dB to be approx. 1.58KHz. with inductor L1=0.1H.
Note that V1’s phase is -90 degrees.

The result however is 158 Hz for both uSimmics 5.8I  and QucsStudio 4.3.1
If L1 is changed to 0.01H than we get 1.58KHz

I did run the circuit in Qucs 0.0.19 and also in LTspice, which gave the expected frequency.

How can I explain the decade difference between the simu;aters.
