This suddenly started happening, and I don't know why...But I suspect that I bumped something. Does anyone know what may cause these icons to appear?

Beside "Create New Folder" and "Create New Document" and "Paste" have never had these icons beside them before. I don't mind them, but I want to know where they came from.
This happens on Ubuntu/Ubuntu 2D, GNOME/GNOME Classic, and Cinnamon desktop environments.
Thanks all!
