If those are the world aligned bones then you will need to edit the mesh on the widgets.
You can’t slide them on the Z axis with that version of the BoneWidget add-on.
There’s a newer version coming this week in which you can. That is on the development branch at the moment.
It will be pushed to the master branch in the next day or 2 as soon as I finish up making the video for it.
(But the code is ready to go)
So you can download the newer version.
Or just edit the meshes to match.
