{url_parameter} for email always adds "mailto:" text

I tried using url_parameter to pass the parameter values to a page through a link button.
On my Thank You page the sample link with parameter is:

https://test.com/thank-you/?first_name=test&last_name=test&street=11%20Polson%20Street&city=Toronto&state=NY&zip_code=10010&email=test%40gmail.com&phone_home=8089999999

In a link button on Bricks Builder, the custom URL link is:

https://www.redirecthere.com/?fname={url_parameter:first_name}&lname={url_parameter:last_name}&address={url_parameter:street}&city={url_parameter:city}&province={url_parameter:state}&postalcode={url_parameter:zip_code}&email={url_parameter:email}&phone={url_parameter:phone_home}

When I hover or click the button the link looks like this:

fname=test&lname=test&address=11%20Polson%20Street&city=Toronto&province=NY&postalcode=10010&email=mailto:test003@gmail.com&phone=8089999999

The URL parameter value for email always adds “mailto:” on it. Why is that? Is there a way to show them email in plain text?
