Atthough the inductor "loss" resistance has been suggested in the discussion by contributors, you should be clear about it's effect to drain part of the source current from the parallel resistor in resonance to feed the losses. Both of your plots have the 13 ohm series resistor. But with ideal L and C, this effect can't be seen. Thus I didn't understand which case you are describing. At least, you don't show a plot where it can be seen. My simple guess is, that you confused the simulation cases. Otherwise show the case, where the resistor current is considerably smaller in resonance, with ideal L and C elements.
