What brand of template material are you using? I have found that doing at least a second pass at cutting template material does the trick. One easy way of doing this in WinPCSIGN is to select your entire design and choose "Duplicate" from the "Edit" menu. The keyboard shortcut for this is Alt-D. That will create another copy of your design exactly on top of your selected design. Now when you send the design out to the cutter, it will cut each circle twice.
