Description of the issue:

It's a bit hard to explain what's going on, so I'll be explaining how I have arrived to what's shown in the screenshot.
There's a Cloche loaded with canes, which then was clicked on with the pick up key to copy its configurations. If the top half of the Cloche is clicked, upon placing the new cloche, it will display like the glitched cloche on the right side, where both bottom and top halves are using the dome model. I've managed to make the cloche have two base models instead, but can't reproduce that this time. Breaking the bottom half of these glitched cloche won't destroy the top half as you can see on the rightmost cloche.
