Thank you for your answer. I checked the settings you mention, even changed to sdummy, but that did not remove the extra instances. However, at some point they disappeared, but I can't tell for sure what I have done.
In the mean time, I took a different approach. I have manually instantiated the inductor, then I ran LVS to confirm the sync with the schematic. It worked and I've been able to run and plot simulations for the ideal schematic and the extracted circuit that includes the parasitics. The differences are visible.
