can't open Windows desktop Libraries

Question

I noticed a few days ago that the Icons for my Desktop Libraries ( Music, picture, documents and video) had changed to what looked like a plank page with a curved arrow at the bottom. the titles now read something like ( Music.Library-ms). I tried clicking on these icons to access the lobrary files but nothing happens. I tried deleting them then choosing restor library default but it didn't work. not sure how to fix this. a couple of my desktop shortcut icons are doing the same thing, particularly my Desktop documents shortcut.

any help is appreciated!
