Not possible to insert Multiple EV SSL Certificate to OVH Hosting

Hello everyone,
I bought a Multiple EV SSL Certificate from an external company (SECTIGO) and I want to put it in my hosting.
The Multiple EV SSL Certificate is for the both domains (example names):
1. xx .de
2. yy .de
Each domain have own hosting. The both hosting are supported from OVH.

When I try to add the Multiple EV SSL to hosting xx dot de occour the error as follow: "An error has occurred ordering an SSL certificate. (This fqdn 'yy dot de' is a wildcard and is not in attached domain list, abort)"

When I try to add the Multiple EV SSL to hosting yy dot de occour the error as follow: "An error has occurred ordering an SSL certificate. (This fqdn 'xx dot de' is a wildcard and is not in attached domain list, abort)"

Could you please help me what I can do in this case?

Thank you in advance!

Kind regards
