Thanks for the measurements. It appears you may be measuring some capacitance in the coils, thus the charging effect. Try measuring the capacitance of the coils. They are capacitively coupled.
I tested my Rodin coil and my Starship coils, always positive unless I reverse phase the B winding, so that means the inductance is zero or almost zero. Meters do vary and I think that what happen to you. But it's very important to post things like this, many thanks for your work.
My little inductance meter, for example can measure in the range 3uH to 500uH for one setting and 100uH to 5MH in another setting. An inductance outside those ranges would produce a BOGUS result on the display.

my one rodin coil has the following values,
winding A = 0.280 mH winding B = 0.280 mH
in series = 1.057 mH

check the specs of the meter. They can only measure inductance in a certain range. Negative values are a FAIL!
