Hello Christian,
There are several reasons why certificates are not showing on your Microsoft Certification profile.
1. Certificates are posted on another profile and you are currently accessing a different one.
2. Requirements for the certificates are not yet fulfilled.
3. The Microsoft Certification profile is not yet associated to your Microsoft account.
