EFD Pro Surface Plot

The temperature surface plot in my EFD Pro looks a little bit abnormal, as per following attachment.

The highlighted region show highly discontinuous contour, no matter how fine the mesh I used in that region. And no matter how many level of legend I used to display the contour. There is always discontinuity in contour.

Also, there is always discontinuous contour between solid and fluid interface.

I am a user of CFdesign and Icepak as well. I never see this problem when I am using these 2 softwares.

Is it due to the averaging method of EFD Pro? Can I resolve this problem?

Hope somebody can help me on this.
