I'm new to tabbing in MV and trying to figure out why I get a zig-zag border cut on one edge of my parts where there is a tab placed. I thought it was an issue with my lead in/ lead out of the part, but it is doing this weird cut on one sides. My lead in is on the bottom of these parts in the photo. Cutting on a Biesse Rover.

 I used tabs in other software and never had any issues.
