What destination did you use to restore the files? Did you select to restore the original folder structure?
I suspect that when you restored the backup catalog, you did not choose the original destination or hiearchy. So, if you are expecting your files to be in the OneDrive local folder, they have in fact been placed elsewhere and you probably have a duplicate set of images on your hard drive. You can easily find where the catalog backup has restored the files by right-clicking on a file and choosing to Go to Folder. You can then see which folder contains the catalog file in the My Folders tree view.
