I created a nest of parts using True Shape Nesting and Automatic Nesting Tabs. The composite drawing looks good with the Tabs, but when I look at the G-Code, some of the tabs are missing. This seems to happen occasionally. Is this a bug in my Post Processor? Has anyone else experienced this?

Also I tried to added more Tabs manually to the above nested parts, but when I update the G-Code from the drawing, no new Tabs were added. Does adding Tabs manually only work for "center-line" routing? If so, why only "center-line" routing if Automatic Nesting Tabs works with True Shape Nesting, which does not use "center-line" routing?
