Ah right! Okay, I think I understand now - the liquid water experiences a temperature drop right at the interface, but the vapor temperature will also drop at the interface from heat transfer. And since the vapor has a much higher thermal diffusivity, we see it spreading much more in the vapor region than the liquid region.
I generated some new plots (below) and i think it confirms. Thank you very much for helping me understand this!
Liquid temp:
Interface temp:
One last question I do have though - an enthalpy plot shows that the air has an enthalpy of ~1,860. The air's standard state enthalpy is 0, and the reference value for the case is also 0. Shouldn't air's enthalpy be 0?
