Mautic 3.3.3 reports - filter date range in UI

I’ve created a report in mautic with “contacts UTM codes” as the data source, with no
When I open the report and click the dropdown button labelled “filters” and set a date range, it has no effect on the report (no increase or decrease in the number of rows in the report), though the contacts have visited pages and the utm codes were recorded on various dates.

Which date field range does this filter’s date range set ?
Thank you in advance.
