Hm, I see your problem. You have 2 shells, an inner and an outer shell. They are printed and in between infill is printed. But since it's at some percentage, it only prints at certain locations, jumbing from one place to another. Enabling combing would help a bit, but you probably want to use another setting, my bad in advising spiralize.
You need to check the black magic setting: only follow mesh surface. That's what I use for cookie cutters, it skips infill, top and bottom layers
