K1C 0,08mm layer height becomes 0,16mm

Regarding my K1C (0,4mm nozzle) I noticed today that when I want to print a model with a layer height of 0,08mm (supported by K1C) the printer prints with a height of 0,16mm. Looking in fluidd when I start printing I see half the amount of layers then when checking the model in Orca slicer or Creality Print. Checked the generated G-code and indeed the layer height is specified being 0.08mm for each layer. Any idea what the cause is? When printing thicker (0,12, 0,16 or 0,24mm) layers then the number of layers in fluidd and OrcaSlicer is equivalent.
