The QR code generated by the Wikipedia link you shared it's not the same as the "SEPA Single Payment", you can see the original request for including single payment here: https://bugs.launchpad.net/qr-tools/+bug/1741772
Unfortunately, I can't read German, so I don't know if the old one still applies.
In any case, QtQR has reached its EOL, but if you want to send a PR / patch I'll happily review it and add it.
