Lightburn is filling the wrong portion of a logo. (Longer Ray5 10w - HP windows 10)

Good day,
I am new at lightburn but cannot seem to figure out how to fill inside the HB and the lines so it will engrave the HB but leave the letters and the inside D shapes of the B untouched. Anytime I fill, it just fills the letters and the inner sections of B. I have also attached the image that I am trying to engrave. I want to essentially engrave the white portion. Thank you for your help in the matter!
