Help! No longer leaving tabs

Have not changed anything from yesterday but today its no longer leaving tabs behind. I have been successfully cutting 1mm material with cut depth being 1mm and a 2mm tab height. Today, using shapes I frequently cut, its showing the yellow spots in design but simulation view shows no Z movement for the tabs. I then tried to lower the tab height to match material thickness, but it reverts back to 2mm. Since these are shapes i cut a lot, I thought to try to import the SVG…nogo…as now cut path settings are now imbedded with the svg,and i dont recall that being the case in the past
