Not able to drill down into Signature details

[learner012]

Each signature module has the ability to drill down further into details and provide that information upon clicking on the specific signature results.
But the signatures triggered does not provide any other information. Also the links are also not clickable. Am I missing out on any configurations to be done?

As a reference, please check the screen shot below which states Why the signature "Installs itself for autorun at Windows startup" has triggered.

For me it's just show the signatures matched. I am not able to drill down further.
