no data returned for web filter violation report, but shows up in dataset

I have built the following data set:

Log - Web Filter

select $calendar_time as time, srcip, catdesc, dstip, hostname from $log where $filter and action='blocked' group by time, srcip, catdesc, dstip, hostname order by time, srcip, catdesc, dstip, hostname

I built the chart, (see image) but when I go to run the report, it returns no data, even though I matched my report to my dataset testing - last 1 day - same firewall. Can anyone help me figure out what is causing the disconnect between the data set and report?
