When I select "sort by name" in the app, the app sorts by name but separates the folders and other files. It puts all the folders first. Why is it doing this? There's an option to "sort by [file] type", so why is that option encroaching on the name sorting? Is there another setting I don't know about that is causing this behavior? It was not always like this and I could have quick reference PDFs at the top of the alphabetical list just by putting an underscore on the beginning of the file.
