Actually, it would be most helpful if you could take screenshots of the properties (showing filename, etc) and main page of the tag editor for two of the duplicated tracks.
I actually think I figured it out, thanks to you. I realized that I had 'auto-organize media files' as well as 'continuously monitor' selected, but that wasn't the problem. The problem was that they both directed to the same folder, but oddly enough, in different ways of getting there.
I use Google Drive, so I think that's what messed it all up and confused everything. I directed 'auto-organize media files' to C:\Users\User1\Google Drive\Music\ BUT 'continuously monitor' was directed to \\PC\Users\User1\Google Drive\Music\ and even though they were both directing to the same folder, for some reason everything duplicated like they were two different folders.
All I can say is thank you, because it's been driving me crazy for a while now. I just hope this is actually resolved.
