Multi Select can't delete un-build item anymore

I remember being able to use the tool to select walls that have been planned out, and using that to delete a large group. That doesn’t seem to work anymore on unbuilt items in all of the categories. I didn’t see any posts on this so hopefully I’m the first and its not just me.

I’m running the version 1.1.2 with the DLC Cats and dogs enabled.

This was true prior to V1.1.2. and I’m fairly sure it’s been this way for a few versions now. I don’t know if it is a bug or working as intended.
I agree though that it would be nice to be able to delete the un-built walls.
