No Alert Details

I have created two alerts to detect and advise of abnormal network traffic, this being a high percentage of UDP or ICMP traffic. My reasoning being that these would indicate something bad happening on the network given 95%+ traffic would normally be TCP. So I have two alerts, both the with the alert criteria set to 'port' and 'icmp' or 'udp', with utilization thresholds set to 15%+.

Testing and setting the utilization low to trigger an alert, NFA detects and reports but when you click on the View link, you get a HTML snip for an input type of threshold and nothing else.

Is this a bug or is it not possible to alert against IP protocol utilization?
