Traffic data in PostgreSQL

Hello, i have a problem with dataset in Fortianalyzer. When i search traffic logs in Fortianalyzer under "LOG-VIEW" and "Traffic" i get different result than using Dataset Query in Report Definitions.

Are these queries based on different databases / data sources?

I run the following SQL in Dataset definition:

SELECT policyid, dstport, proto
FROM
$log-traffic as l
WHERE
$filter
AND policyid = '681'
group by policyid, dstport, proto
order by dstport

but this does not return the same ports like searching in Analyzer Log Traffic view when searching with

policyid="681"

I selected the device name in both search scenarios, in the drop down fields.

My question, from where does the difference result and should both query types return the same result?
