What number are you entering online? If it's not an IBAN but something starting with a 4 or 5, you're very likely using Visa or Mastercard, or possibly a domestic scheme. This is not the same thing at all as a direct debit, which nowadays runs on SEPA Direct Debit rails.
The Digital Euro does not exist yet, and Wero is yet another scheme (settling via SEPA instant credit transfers, I believe, but that's more of an implementation detail and doesn't change the fact that it is its own scheme with its own rules).
