Links with dynamic tags that in curly brackets &utm_campaign=${UNIVERSAL_SITE_ID}
become &utm_campaign=%24%7BUNIVERSAL_SITE_ID%7D
This only happens on one site.
Tell me how to fix this?

This is XSS protection. To protect against inserting javascript scripts into url. It is better to come up with another way to obtain the information you need, but leave protection.
