Incorrect layer number and layer height shown in Preview mode and incorrect M600 placement

[Blom69]

Version

Version 2.2.0+win64

Windows 10 build 1809

Prusa i3 clone with Marlin

Behavior

In Preview mode the slider on the right display the incorrect layer number vs what is output to the gcode file in the custom gcode:
; #[layer_num]
; Z=[layer_z]

The layer number shown in the slider is 1 based where the [layer_num] variable is 0 (zero) based.
The layer height shown in the slider does not take any Z offsets into consideration and actually starts at -0.20 (for 0.2 layer setting)

For example, while the slider shows 1.30 (6) the custom gcode mentioned above outputs ; #5 and ; Z=1.9

I use these values to find the correct place to manually add the M600 filament change command.

The option to add a filament change via the slider is even worse affected.

In the above scenario it places the M600 at layer #3 so it is way off.

Other than these two issues I love the software.

The layer ID in the G-code is zero based. I don't think this is an issue.

Would you please provide a 3MF to reproduce?
