[4.5.0] Hole for bolt-nut slicing error

Application version 4.5.0

Platform

Mac OSX 10.15.3

Printer AnyCubic 4Max Pro

Reproduction steps

import screw nut STL into Cura
when placed flat on print-bed and sliced, the hole is not properly sliced and is covered over
when placed vertically on print-bed, the hole is properly sliced.

Actual results hole is filled with material

Expected results hole should be free of material
