restore safari reading list in high sierra?

I accidentally cleared all items in my reading list in Safari and cannot seem to restore them. I checked my iCloud settings, which showed no archives. I also attempted to restore an earlier version of the Reading List Archives folder from Time Machine at ~/Library/Safari/ReadingListArchives. but when I launch Safari, no reading list, and for some reason the ReadingListFolder deletes itself from the library. Not sure what's happening, any advice appreciated.
