Inductive Energy transfer via two small Coils

Hello everyone,
I'm new to comsol (6.2) as i use it for my bachelors thesis. I want to simulate wireless energytransfer via two coils (AC/DC Module) and face nothing but problems. I watched the tutorial series "Modeling Electromagnetic Coils" as a basis.
Currently i try to get the most basic simulation in my sizing to work, but i get physically impossible results (negativ Power, Inductivity, Resistance, wrong looking curves). I have spend immense time on mesh refinement, but it doesn't change anything. Also i found that the mef and mf simulations vary by multible magnitudes, and the mef simulation generates a "reverse" skin effect at high frequencys (even tho as of my knowledge mef is better suited for high freq?), and I'm completly lost and questioning my brain even existing.
Does anyone have some tips or even solutions what I may be doing wrong? Or in general, what do you do if your simulation converges but is nonesensical?
