This leaves power connected to the "off" core via the capacitance between the cores for the whole length of the cable, and you can see half the supply voltage via several hundred pF, capable of sourcing tens of microamps. AFAIK those heaters are pretty simple and cycle elements on/off to maintain temp instead of using a faster PWM - no way around the source of the problem - maybe a tank heater?
