In our dashboard utm_source, source, ref will be stored as utm_source. But sometimes both parameters are used. To give you control over which parameter we should store you can enable strict UTMs.

<script
  data-strict-utm="true"
  src="https://scripts.simpleanalyticscdn.com/latest.js"
></script>

This will only allow for the following UTMs to be used:

utm_source
utm_medium
utm_campaign
utm_content
utm_term

The parameters source, ref, and more will not be collected.
