Deleting distribution history should have likely done the trick However, please submit a ticket to QSupport so the team can access the dashboard to review the backend for a better evaluation.
In the meantime, for a quick fix. You can try filtering page with 'Email Sent Time' on page level. This would work more accurately if at least the test distribution and live distribution dates do not coincide.

It makes no sense why the system would retain details of test data in the response funnel after it's been removed from all other areas of the platform. In instances where one can't apply a filter (as in my case) it renders the response funnel rather useless for reporting purposes.

Reviving the same topic after many years. Looks like nothing has changed functionality-wise and we still cannot use the dashboard to display the numbers correctly...

Hi @msr

Note that Respondent Funnel records event data as events occur, and will not update if contact data changes or is deleted in the future. If you delete distributions or contacts, data from these deleted fields will still be present in Respondent Funnel.
