incorrect simulation results (LC resonance)

https://www.circuitlab.com/circuit/7y8f2dz7m582/rlc-v2/ provides correct results for maximum impedance.

https://www.circuitlab.com/circuit/37ph32kgctdp/rlc-v/ is the exact same circuit and provides incorrect results for maximum impedance.

I just ran both simulations (Frequency Domain) and get the same result on both plots. Both show about -25.21 dBV in the neighborhood of 9.75 kHz.

What are you seeing, and what are you expecting?

Yup, I see same result now. I wonder if I was imagining before.
