The "registrar" and "affiliate referrer" settings on your account have no longer any meaning since it was upgraded to LTM. You have been set as your own Lifetime Referrer, which means you receive 80% of your own fees as cashback.
If you create accounts yourself, you set *their* registrar and/or referrer to your own account, to receive cashback from their fees.
If you use your account to refer users to another registrar (like OpenLedger), that registrar will set your account as "affiliate referrer" for accounts created through your referrals.
