Bug? Doesn’t display GET value along with UTM parameters

Hi,

I would like to pass the specific GET parameter in the URL to email. Here’s my setup:

Form section:
[hidden v default:get]

Mail section:
Campaign: [v]

When I submit the form from this URL, everything works perfectly fine.
https://domain.com/?v=1

It works when I use this URL as well:
https://domain.com/?v=1&utm_source=abc

However when I use the full UTM tags, somehow, the v parameter doesn’t pass and I don’t get any value to my email:
https://domain.com/?v=1&utm_source=abc&utm_medium=def&utm_campaign=gef&utm_term=hji

It is really weird as I don’t know where the problem is. Maybe it escapes once it recognizes UTM tags?

I tested with &gclid= paramater as well and it also didn’t work.

Any idea what is the issue?
