Assets failing to cut or delete when selected using drag select function (x)

Describe the Bug
I have only noticed this in the Aberation block set, and have been unable to replicate with any other tile set. I feel this has something to do with the quarter triangle wall segments.

When selecting a section of assets for deletion or cutting the assets fail to delete or cut dispite showing a response on screen when selected prior to executing the cut/delete.

To Reproduce
See below

Screenshots/Videos/Twitch Clips

I will send through a link to this build to perform the below test. using the castle ruin block below the red square to the right of this image (while making sure the sign is facing you) , start a selection box on its presented facing and drag it across the tower section. Capturing just the top half of the tiles as displayed below. Extend this box up to finish the cube selection.

Once selected either delete or cut the section. you will see the tiles have not been removed while the block and red square have. I have been unable to perform this test with consistant result, its seem that there are times that the blocks delete/cut and other that they do not, my testing generally failed however in the above example.

I have also provided some twitch clips of me doing this too.
