They are connecting from the registrar directly to you. CloudFlare was only a way to test the domain. It works fine with Ceiarsis.info but wrong with the other two that have the alert on Greeny Host Host panel as the nameservers do not point to Greeny Host Host.

Both of these domains still have DNSSEC active;
DNSSEC: signedDelegation

Additionally, they both have this, currently:
Domain Status: clientUpdateProhibited https://icann.org/epp#clientUpdateProhibited

Which means that any changes you make with the registrar are not likely to have any effect – including disabling DNSSEC.
I would suggest reaching out to the current registrar to see if they can get this resolved for you – as DNSSEC will need to be removed by them, most likely.
