Z axis shown on the software doesn't match with the machine

Hi, I just recently baught the A20T from Geeetech. When I trying to print, the z axis seems match in the heating stage. However, when it starts to print, the first layer shown on the software is 0.15 mm, but on the machine screen is 4mm. So the extrusion is floating in the air and doesn't print properly. Can anyone help me pls?

    Check the commands at the start of the gcode until first lines. Normally slicers generate a Z move to first layer height which is not 4mm. But if it contains G92 Z0 it shifts Z. May also be some other gcode or one move was not executed.
