Multiple copies of the same folder showing on Windows Explorer, and some of them are empty

[LynneChap]

I use OneDrive. In Windows Explorer on my PC I now have multiples of the same folder names and many of them are empty (the one I am looking at has 10 copies). How do I sort this out and just have one file?
Thanks
Lynne

Here is an image of all 10 copies of one folder open on the desktop
