Hi Wendy thanks so much for reaching out,
we'd love to look at the database, you can put it somewhere and send me a private link, can you also run a consistency check on it? The number reported in statistics are only the high-id-watermark not actually nodes, But if you also see them in cypher with something like "match (n) return n" then something is off.
