I am seeing some strange behaviour here. Attached is my current file, some additional operations but it is the PathShape which looks strange.
Just playing with Z on SketchEngraveLines, I can change Z in Attachment but not in Base. If I change Z in Attachment then Z Base changes, but not by the same amount, except that if I change it to zero then Z Base does not change. The g-code Z seems to be the difference between the two.
I assume that this is a bug, or have I missed something.

This is not a show stopper for me, I can fairly easily reset Z on my machine to compensate.

Please go back in this topic and read carefully what has been said before. mlampert has mentioned a cyclic dependency, and I have shown how to remove it and uploaded a corrected model.
If you decide to continue with your erroneous model you will get these strange results.

Inside of a body you can only change the attachment offset. This adds to the placement of the attachment plane.
