Sorry, just realized I misread your question. We’ve had a bug with the values of the select dropdown element and thought you were referring to this.
Actually the behavior you’re seeing when you bind the query string to the URL is NOT a bug.
We are indeed transforming and displaying the property-id value as a string when you bind it to a URL as a query string but that’s necessary because query strings are strings.
I’ve added your comment to our user research as this might be confusing to users! Thanks a lot for taking the time to bring it up. We really appreciate it!
