Reset SSL Certificate state

Site: gleeful-griffin-1dd569 Custom domain: test.kingsfcu.com
Issue: DNS verification succeeds consistently, and Let’s Debug (letsdebug.net) reports “All OK” for the http-01 challenge. However, clicking “Provision certificate” returns: “certificate parameter is required when updating an existing certificate.” This appears to be a stale certificate record on the backend. Could you please clear/reset the SSL certificate state for this site so I can provision a fresh Let’s Encrypt certificate?
