I have observed the printer, and it is lifting to 6mm at 50mmpm and then from 6mm to 20mm at 300mmpm for bottom layers, i.e. it is performing exactly as per the settings.
If I decode the .ctb to a zip file and check the run.gcode file, I find the following:
I slice in formware to a .ctb file, with the following bottomLayerLiftHeight and bottomLayerLiftSpeed settings:
;zSlowUpDistance:6 ;normalDropSpeed:300 . . . ;bottomLayerLiftHeight:20 ;bottomLayerLiftSpeed:50

In other words, uv3dp has transposed these two settings.
