P12 file 0byte emtpy OPENVPN cert Manager

[tempes2k]

Hi Guys, hope anyone has an idea or hint.

i would like to use OpenVPN on my "2.4.2-RELEASE (amd64)"  i have upgraded from 2.3.3.
It is not my first time to configure OpenVPN.

The client export Utility exports everything well except the p12. file. It is 0byte (empty).
The same issue is also when trying to export from cert manager.
The certificates do not have any private key symbol as you will see in the screenshot.
The P12 file is empty.

What can i do to fix this problem.
it is no option for me to reinstall the system.

hope anyone has an idea.
how can i check what is going on.
