What you are observing is normal and expected. Even after proper priming, after several puffs the top of the polyfill will have the appearance of being dry.
The above image is a cutaway diagram of a punched cartomizer. The red arrows represent juice flow and blue arrows air flow. Suction pulls the juice down to the bottom of the carto where the heating coil is, as well as pulling juice from the tank. Wicking from the tank will not keep up with keeping the top of the polyfill wet, but it doesn't have to.
As long as the polyfill around the heating coil stays wet, there will be no burning of the filler.
