Multi bodies and hole wizard

I have an issue with a 3 body part.

When i use the hole wizard i actually cut one of the bodies into 3 bodies, or at least that was what i thought it would do. But only one body remains, and i can only guess which one.

I have no idea how to put it so that it keeps all 3 (and thus becomes in total 5 bodies).

Link to demo part to isolate the problem.
