Empty utm's from embedded form on lead records
Recently embedded a form on our website using hidden utm's, but when leads fill out the form, the utm's do not appear.
Form with hidden utm's

When I look at the activity log, I see the utm's are there

But the utm's are not populating on the lead record when the form is filled.
I do see that on the activity log the query param is missing, but the url for the form does have the query params: https://xxxxxx.com/#?utm_medium=website&utm_source=organic&utm_campaign=contact_me
What am I missing to make this embedded form populate the utm's?
