That’s just an on/off switch. I see your ticket, reopened it and added a link to this thread. Did you enable DNSSEC via the blue button on the DNS page or that grey/green toggle on the registrar page? I am not sure if it matters but am curious.
Also curious while we wait for someone from the team to respond on the ticket, I noticed your DNS records are , again not sure if it matters, but if you proxy them by click to turn does that affect the stuck DNSSEC process?
This issue has been resolved. Our team has removed the old DS records for you that was causing the issue. Sorry for the delay here and thank you for your continued patience.
The team also mentioned, you have DNSSEC turned off, but if you enable it the new record should get enabled this evening.
