That's strange. I saved them all the same way. I just imported it into SheetCAM and they all show up for me. Are you sure you don't have some of them hidden? Each flame has it's own layer.
Glad this was solved! If you had said it didn't work at all I had a couple things to try, but only two showing up didn't make sense. I'm really happy it's working for you now. I was really scratching my head to trouble shoot this file.
