I have a folder in a Mac desktop synced to a Windows Phone 10. The folder name in the Mac is “Books”, the name in WP10 at first was also “Books”. At some point I removed this folder in WP10 and started over (just to learn how it all works). Now that same folder shows up as “Books (2)” in WP10. Back and forth (both with settings and help center) I can not find how to rename this folder back to “Books”, as it is in the desktop. I would appreciate any help, thank you.
