Incorrect gcode generation for nested patterns

When nesting mirror pattern into a linear pattern, Fusion 360 generates the correct preview, but incorrect simulation & gcode. Screenshots attached (several in a .zip archive), as well as the f3d file and generated gcode.

At the glance, your first clamp is done using climb milling but when you make mirror pattern of that tool path, your second clamp is done in conventional milling.

It depends on material in question how that will affect the outcome, I would suggest programming clamp shown in blue separately if that's the only one oriented that way.

That's a good point about the climb versus conventional milling when dealing with the mirror pattern. Using a circular pattern to make the second piece, and then linear-patterning the result works as well. Still curious that the mirror pattern fails when nested in the linear pattern.
