Cooling Head Lift

Is the cooling head lift feature not supported for the Airwolf line of printers? I’m printing some pieces with very small peaks and there is no difference in the operation of the printer with “cooling head lift” checked or unchecked. I’m certain the printer is capable of it as one of the test prints that came supplied on the sd card when I originally purchased the machine executed the cooling head lift feature during the print. It doesn’t seem to work through the Astroprint Advanced Slicer Settings though. Perhaps there is a second feature tied to the cooling lift that I have to modify or activate as well?

Thanks for any info/advice.
