New flowrate tiles test sets inappropriate layer height. They also grow in size and overlap when slicing

How to reproduce

1. Start a flowrate test, any option will do.
2. slice the plate

Actual results

first, a number of parameters are changed, which include setting the nozzle height to an inappropriately high number for the nozzle diameter (ex. 0.4mm for a 0.4mm nozzle):

Upon slicing, the models grow in size suddenly:
Before:

After:

Slicing preview:

These do not print properly, as the layer gaps are too large for proper layer adhesion. It is useless for flow cal because the huge gaps cause massive under extrusion on anything other than the first layer.

Expected results

I would expect the flow tiles to not only retain their original as-sliced size (and not grow), but also that the calibration would not alter layer heights unnecessarily

more developments: the bug described happens inconsistently, and does not always resolve itself when restarting the slicer. Sometimes changing to a different printer profile, and then back again fixes the issue.
