Link Info missing in Links panel in InDesign

I have an Indesign doc open. When I click on an image in the layout that image should be highlighted in the links panel and details appear in the link info panel below. Now it doesn't. If i close Indesign sometimes when i re-open it works.

Could somebody please tell me how to have the link info panel active when i click on images in Indesign doc
