GUID of documents are shown while navigating KM Contents
i've deployed a PAR file in my portal platform SP16. When i navigate the mouse cursor on any visible document/content of the repository through Content Administration > KM Content, the GUID of documents are shown as ToolTip. now my question is, how can i configure it so that it could show either the name of that document as ToolTip like other default repositorie's documents do.
Is there any coding effort required or only some configuration steps will make it possible and also explain the required steps.
Thanks in advance,
