Delete All Listings

When using the toolbox in the admin dashboard.
If you choose Listings Only Delete All Listings

It does indeed delete all listings correctly, but it also does something to the categories.

It would seem that It also removes all the Parent categories leaving behind all the child categories and it is also leaving them as Orphaned so you cannot manage them from the category view.

You can still assign them to products but they don’t display in the admin listings>category area.
I was cleaning up the demo data in the BT theme, I have tried it now on 3 different sites an it has trashed the categories in the same way on all of them

Thanks
