SSL certificate not updating via Plesk GUI

[DennisAm]

I have a few SSL certificates that have almost been expired. Therefore, I renewed them and received new cerfiticate files.
However, when I try to update them in Plesk, some of them aren't updated. These are the steps I take:

1. Go to the subscription that the certificate is for
2. Go to "SSL Certificates"
3. Click on the existing certificate, so that the screen "Change Properties of SSL Certificate" opens.
4. Upload the new .crt file.
5. Plesk returns "The SSL certificate was successfully updated.":
   

Then, when I open the IIS Manager in the Windows Server GUI, I still get the old certificate:



Instead of



The only way I can get it to work is to:

1. Go to SSL Certificates.
2. Create a new certificate, upload the old private key and new .crt file.
3. Assign the certificate to the domain.
4. Now, the new certificate is assigned correctly and served by IIS.

Again, this is only the case for some of my domains (about 50%). For the other domains, I can simply update the SSL certificate by requesting a new one and uploading it to the server (following the steps mentioned above).

I checked Plesk logs (after having turned on Debug mode), but there's no errors in there:

What can this be? Can we consider this to be a bug in Plesk, since no errors are given by the system?

Server: Windows Server 2012 R2
Plesk version: 12.5.30 Update #13

These are the correct procedures I know ...(If you used the OLD private key to order for the new SSL)

Thanks for your reply!
Yes, I did use the old private key. Again, it works for some domains, for some it doesn't...
