Force removal usually end this way, unfortunately. Assume you know this, but just in case, always try to exclude Z-Wave devices (put hub in Exclude mode, put device in exclude mode) before you resort to a force remove.
If the hubs built-in Remove option on the Z-Wave Details page fails to remove the left-over nodes from the force removal (we call them "Ghosts") then take a look at the post below for more details and options to remove the ghosts.
