vROPs Manager UI not listing inventory as expected
When I click on Environment in the UI and say vSphere Hosts and Clusters and expand the vCenter Adapter, it doesn't list anything. It's the same under Reports. But it has definitely collected the data and if I try to run a report and change it to All Objects, the inventory tree is there but I do not want to run it from All Objects. It's also the same under Environment that I can expand the vCenter Adapter and list the inventory.
Going through the various tabs on the Dashboard lists all the relevant information also.
Have I missed a step where it is not listing the applicable inventories under the categories?
