I have added URL parameters to the global exclude list based on How do I exclude URL query parameters from the URLs tracked, and from Pages reports? - Analytics Platform - Matomo. However, the parameters are still being written into the db.
Specifically I’m trying to avoid certain parameters being written to the referer_url column in piwik_log_visit.
The FAQ language “When you specify one or several parameters to exclude from your URLs, note that it will only affect data going forward. (URL parameters will not be removed from your historical data and reports)” implies that when I add parameters to ‘Settings / Websites / Settings / Global list of Query URL parameters to exclude’, those parameters should not be included going forward.
I updated approximately one week ago to block a set of parameters, but they are still being recorded in the db.
Have I misunderstood the way that this function operates? Is there another way to prevent specific parameters from being written to the db?
