Issues with multi color printing settings?

Tying to print my first multi color object. Its eventually going to be a highway shield.
3 times so far and each time it is printing strange lines and each time they are different.
I’m just a couple days into using the P2S and 3D printing in general, so keep that in mind.

I have printed other pieces from MakerLab (scrub daddy holder, dinosaur, scraper, tiny duck) without any problems with them being 1 color prints. I guess I’m doing something wrong with the infills or something. Appreciate being pushed in the right direction to fix my issue.

Youll need to share a screenshot of the intended object or the 3mf file, it isn’t clear what it is supposed to be nor what is wrong about it

Sorry. Guess I should have included what i’m trying to print

My guess is it is filling in the internal space with just whatever-it-thinks will create efficient lines. It’s all buried space. Is it actually a problem? I think if you just let that print go, it would be fine.

Slice it, go to preview tab, and use the right side slider to confirm that what it was trying to do is what you saw, and that if you let it go, would it make it fine?

If you see odd geometry IN the preview, it will be IN the print, so use this preview pane heavily when you are trying to analyze prints.
