Sheetcam pocketing

I would like to pocket between two contours. When I run the simulation it ignores the inside contour and pockets the whole area.
Is it possible in Sheetcam to run this operation and not remover the material in the middle.
Any thoughts? Thanks

Do you have the two contours on the same layer? if so, it should pocket the contour and leave the island.

They are on two different layers. I will try that today. Thank you.
