Also, it's considering "extra books" those records that it recognized before, when I first ran "Restore Database"
very strange
Restore database will add books to the newly-built calibre db only if they meet a very strict test: the "calibre_id" in a metadata.opf must equal the number in parentheses found on the folder name containing that metadata.opf. If this test is not met, the folder containing the books is ignored. Example:
Title folder name: 20,000 Leagues under the Sea (233)
Line in metadata.opf: <dc:identifier opf:scheme="calibre" id="calibre_id">233</dc:identifier>

If Google Drive was ever used to sync the library then the number in parentheses will likely be wrong or missing.
