Stl floating

[Alex2099]

Hi,
I just bought this software, when I try to generate the gcode the stl will float approx at 1mm over the bed and the same thing happen during print.
Hereis a screen on software preview.


I've uncheck the Raft options but seems that layer was eliminated but not the movements (I put again Raft when I made the screen during test)
How can I solve it?
Thanks

Kind of need to see the original STL to help.

Looks like the raft separation distance to me
