How do you remove unnecessary boundary lines when exporting to X5 from Deep Exploration 6.5 CE?

I have tried multiple methods, options, etc and am still unsuccessful to remove the extra lines from the vector graphic export.

This is how it exports...and I do not want the lines identified:

Somehow this tutorial at 8:30 shows their illustration perfect without any extra lines (…almost).  I mimic their settings and it does not help me.

I then tried this tutorial (1:55 - 2:56) and it doesn’t seem to have the perfect illustration.  I don’t understand what’s going on here.  Is there no option in 6.5 CE to create a vector graphic without the extra lines as shown in the first tutorial?
