Fields get mixed up

Hi!

So we have been having an issue with CF7 recently. Some of the form submits gets field mixed up in other fields which is a real problem.

Example:

When someone submits a form we get all the form fields plus the utm_medium, utm_source, utm_campaign. We use Contact Form DB to have access to this submissions and all this get pushed to the CRM (Hubspot).

We have been seeing errors in that some submissions get the Phone field in several of the other fields, precisely this utm_ fields. This happens on like 1 out of 10 form submissions.

Normal Form Submission:

Name: John
Surname: Doe
Email: [email protected]
Phone: 0744415699
Form: Course Landing Page Form EN
Page Title: Java Web Developer Bootcamp Berlin
Page URL: https://www.ubiqum.com/berlin-java-web-developer-bootcamp/
utm_source: Google
utm_medium: cpc
utm_campaign: ADW000018-Broad-EN-Coding_Bootcamp

Odd Form Submission:

Name: John
Surname: Doe
Email: [email protected]
Phone: 0744415699
Form: 0744415699
Page Title: 0744415699
Page URL: 0744415699
utm_source: Chemnitz
utm_medium: 0744415699
utm_campaign: ADW000018-Broad-EN-Coding_Bootcamp

As you can see, the Phone field gets replicated into several other fields and we get the IP City on the utm_source for no reason.

We think that this problem might be related to:

– UTM gets blocked or removed by some Ad Blocker or something
– Some weird integration problem with the CRM maybe?

We are out of ideas on how to fix this! Any idea or help would be HUGELY appreciated!
