I'm trying to print a thin part using the spiralize outer contour feature. The dimensions of the final print are good, but there is one issue. Cura is inserting an extra shell/inner perimeter/top layer, where there should be none. Please see the attached images of the gcode preview and of a printed part cross-section. The cross section image has 4 additional double perimeter layers instead of 1 due to the default top and bottom layer settings. I have changed my top layer settings to 0.
