How it used to be is you could hit "select all" and delete your local screenshots with the screenshot manager, but late last year this was changed to also include your uploaded screenshots, many people lost a lot of pictures because of this.

There is no reason for it to work this way, this makes deletion through the manager functionally useless, if I want to clean up space on my computer I have to manually delete the files.

Please change this back, if I want to delete uploaded screenshots I will go to my profile.
