How to fix odd layers in the middle of a solid

Greetings!

I am looking for some guidance. I am attempting to print some tokens for my friend's bar. This seems like it should be very simple, but I am running into an issue that is causing the prints to take a lot of extra time, and also it seems to "smush" some of the layers causing some of the parts to look terrible and get tossed.

This token consists of a 2.6mm thick, 45mm diameter cylinder that I created using prusa slicer. On top of that, I have placed an .STL of some artwork that was provided by the bar owner. I am printing these with 100% infill and ironing on top surfaces.

The odd thing that happens- About halfway through the solid cylinder, it wants to print a 'ghost' image of the STL that's on top of the cylinder. Then it goes back to solid layers again.  If I delete the STL, it's gone. It makes absolutely no sense to me.  Any thoughts or suggestions? Thank you.

Please, save your project as a *.3mf file, then compress that file with winzip and load the resulting  *.zip file here. This way we'll be able to diagnose the possible issues.

RE:

While you are zipping up the .3fm file, you also might ensure you have joined the two objects in Slicer (merge the disk and logo parts into a union).

To your question why is this happening, without the 3mf, my only guess is the logo stl is more complex than it seems.
