You should have gotten an error about a missing og:image when editing that post / page.
Did you follow the Setup Guide and define a default image?
The following FAQ should help explain how WPSSO selects / finds images: https://wpsso.com/codex/plugins/wpsso/faq/how-does-wpsso-find-detect-select-images/
Let me know if that fixes your issue.
