Simple Melting Problem

Hy all fluent users!
I am a fluent beginner and i want to set up a melting/solidification problem. I started with the easiest model, but i still have troble with that.
My model is a cuboid. All walls are adiabat except one. This one is heated (T=600K). The properties of the pcm are all set to constant:
Initial value for temperature: T = 300 K
Time step: t = 2 s
After the first layer is molten, it takes a long time that the melting process continues. There is always some time between the melting of two layers. It dosn't melt consistent. The bigger i choose thermal conductivity and the lower i choose density, the shorter become the time between the two layers (whre no melting is occurring). see the picture attached!!
What do I have to change to get a consistent melting???
Thank you for your help!!
