When an admin adds a media (specifically image) to a node and then deletes the media without deleting the corresponding file to that media, in the file tab in Content, it will show that that this file is used in 0 places. However, when a user adds that same image (same file name), then in the file tab in Content, it will show that the image file is being used in 2 places despite only being used in 1 place (i.e. one entity). We have tested that adding that media/image to another node doesn't increment the count.
It is important to note that this behavior does not seem to affect the performance of the module.
The module settings have been configured that the "delete corresponding option" has been ticked on by default (can be ticked off when trying to delete a specific media)
