How to reproduce

System is set to use 0.4mm nozzle.

Minimum layer height bug

1. From the global process list, select any process that is not 0.08mm or 0.28mm.
2. On the Quality tab, manually change the layer height to 0.08.

Maximum layer height bug

1. From the global process list, select any process that is not 0.08mm or 0.28mm.
2. On the Quality tab, manually change the layer height to 0.28.

Actual results

The Warning dialog opens:
Layer height exceeds the limit in Printer Settings > Extrude > Layer height limits, this may cause printing issues.
Adjust to set the range automatically?

Clicking Adjust and clicking Ignore give the SAME result: the value for layer height does not change.

Expected results

The Warning dialog does not open, as 0.08 and 0.28 are both acceptable layer heights for a 0.4 nozzle.

I get the same error when setting the layer height to 0.04mm with 0.2 nozzle. I've confirmed this should be valid according to the layer height limits in the extruder settings. If I hit "adjust" it doesn't change anything, and if I then try to print I get almost immediate print failures due to nozzle collisions. These collisions don't occur if I use a 0.06 mm layer height.

[Whahahahaha]

Weird part is also how the 0.6mm nozzle only gives this error when layer height is equal to the min value, but not when it is equal to the max value, while 0.2, 0.4 and 0.8 all give errors on both min and max..
