UTM Parameters Not Updating Correctly

[angelocala94]

I've encountered an issue where the UTM parameters stored in cookies do not always match the UTM parameters in the document location (dl param). Specifically, I often observe cases where the UTM parameter in the URL is different from the one stored in the cookies from a previous session.

For example:

Document Location URL: https://page.com/test?utm_creative_format=test
Stored UTM Cookie Value: old_test (value from a previous session)
Expected UTM Parameter (in the pixel request): utm_creative_format=test
Actual UTM Parameter (in the pixel request): utm_creative_format=old_test (value from a previous session)

Has anyone else experienced this problem?
