Node Description is not shown in Description Panel (Classic UI)

Hi there,

I am new to this forum for my applogize if I placed something wrong!

We have installed Knime Analytics Platform in Version 5.4.4 and mostly using classical UI. In the past in the description panel and overview about the function of the node was given in the Description panel. But in our case the Panel is empty, and no error message was identified guiding us to a solution. When changing to the new UI the information is shown in the Information Tab. Any idea about how to fix this?

Kind regards,

Gregor
