Algorithmic Modeling features will always create new bodies -- they will not consume the previous input bodies. So in cases like this where the Algorithmic Modeling feature uses the original part solid as an input, you'll see that original body remain as construction geometry. You can either just remove this body from the MODEL reference set (which will remove any duplicate mass from the part), or use the "Delete Body" feature if you really don't want the body around anymore at all. Does this help?

Can you Please tell me what is the diameter of outer circle.
it seems boolean operation is not working correctly. after boolean(substract), I always need to come back to history and hide the body.
