Hi everyone,
In the 3d Viewer the board layout is OK. I added 4 cutouts in the corners and the 3D view shows perfectly how it should be. But when I upload the gerber to JLCPCB, OSHPARK, or other, the cutouts appear as solid regions.
Pictures explain the issue by themselves.

Is there any other better way to do this cutouts?
Thank you in advance.
