The issue is not quite clear to me. The FileBot screenshot shows the files, and the Desktop screenshot shows the folder names, which of course may very well be slightly different
(which doesn't matter to FileBot).

If you're asking about how to rename both file and folder
(i.e. rewrite the file path) then FAQ #1 will get you sorted:

If you click Rename to rename files, then it'll either work, or give you an error message, if the OS can't perform the operation for some reason:

If you press Rename, and it seems to work, but nothing changes in your file viewer, then that's most likely because your file viewer hasn't updated it's view yet, or may be using stale cached data, which is a common issue when working with remote filesystems. In this case,
Pressing F5 to force refresh the folder view should do the trick. (in bold because that's my best guess for now)
