Wrong Federated-Cloud-ID in cards (contacts)

Nextcloud version: 27.1.4
Operating system and version (eg, Ubuntu 20.04): Linux 5.4.0-104-generic x86_64
Apache or nginx version: nginx
PHP version: 8.2.13

The issue you are facing:
I changed the domain for my nextcloud-instance.
In cards/contacts the wrong (the old one) Federated-Cloud-ID is displayed. It is not possible to change the contact-card (maybe because it is a system contact). In settings, the Federated-Cloud-ID is correct.

I found a simular issue but it doesn’t help: Change Federated ID - :information_source: Support - Nextcloud community

Thanks for any hints!
