Document Library - Tile View Counter

Good morning,

On my document library, in tile view, I was under the impression that the number in the bottom left hand corner of the files was the counter of how many files were nested under that particular folder.

Pic 1 is showing the count at 0. However, there are 5 folders that are nested under this folder (pic 2).

I do have 'Folder Child Count' and 'Item Child Count' on, and these show correctly when viewing the library in list/grid view, just not tile view.

Could anyone advise as to where I might be going wrong?

Much appreciated in advance.

Regards,

Andy.
