Since install of Management Plugin 11.3 I cannot edit Policies anymore, settings not shown

[Wess]

Had Kaspersky Security Center 11 installed when I Installed Plugin for Endpoint Security 11.3.

Normally the Plugins for the Different Versions coexist, but this one Updated the 11.x Plugin already installed before. Outcome: Existing and new Policies dont Show any Settings when you edit the Policies. Policies for other Kaspersky Products work.

In Section most entries are missing:

Even a complete Upgrade to Security Center 12 didnt fix the Problem.

Any Idea???
