Issue with Graphtec CE7000 F-Mark2 (X cut)

[Pideas]

When I try to cut a basic label (two rectangles) on my Graphtec CE7000, using the Cut without Crop Marks checked, I get an X across the rectangle. I cannot see any settings on iMark that would cause this.
Does anyone have any ideas why an "X" would be cut across the label?

Thanks.
