Composite level determine what's dark/clear and the sequence in which the objects are drawn. We have updated FAB 3000 to create a teardrop no matter the composite level - assuming both are the same polarity (Dark or Clear). Here's a screen capture of the teardrop feature now working in those areas, and we'll have the update of FAB 3000 available in a few days.

3. selecting trace and pad (flash)
4. fabrication -> teardrop (chosen teardrop) -> ok
after this step no change occurs, but while manually imported Gerber data able to produce teardrop.
below images for your reference.
