Not an Octoprint Backup

What is the problem?
When attempting to restore from an UPLOADED backup, I am presented with the following error: "Not an OctoPrint backup, lacks metadata.json" I can restore the same backup if the backup is present within OctoPrint and NOT UPLOADED through the browser. It is when I attempt to restore from a backup that is uploaded that I am presented with the error.

What did you already try to solve it?
Nothing yet besides creating this post.

Logs (octoprint.log, serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)
