Campaign - View Results - Cannot drill down the charts

Hello All,
New to SuiteCRM - love the Product !! We have an isssue where we are able to create and run the campaigns – The Chart on View Details shows the details (Sent/Attempted,Opt Out etc) however, we are not able to click on drilldown(it shows though) and the list below (Accounts, Contacts etc) is not populated.

Kind of stuck

Thanks,
Sumeet
