Form: File/Upload creating duplicate Files

Permalink 2 2 Browser Info Environment
On the form block, when using the image/file field. There is the option to choose where the uploaded files go within the file manager, under the options tab when editing the form.

When the selection is set to the default option (file manager), and a file is uploaded through the form, it creates two versions of the file, which are seemingly identical. When you choose to put the uploaded file into a specific folder in your file manager (Such as the "Test Folder" option I have in the screencap), the file uploads to the folder, and a duplicate of the file appears in the default "File Manager" location as well. This only happens when uploading a file through the form, and it works just fine uploading a file any other way.

I've tried this with a couple of different websites, so I'm pretty sure there is something wrong with concrete5 itself. I'm using the latest version of concrete5 so far with both websites (8.5.2), so I'm not sure if this was always happening or if it was a recent regression.
