One transform rule working strange

We have setup a simple rule to rewrite urls:

  1. This is working.

    But strange thing that outcome url looks like this-> https://old.blackbullmarkets.com/en/live-account?cxd=12345-123/ adding ‘/’ at the end.

Could someone take a look on this, please.

And one additional question - could such rule work if old.blackbullmarkets.com would be CNAME?

Where are you seeing the trailing /? Tracing from our systems I can see the URL being created as you intend: Rewrite URI /live-account?cxd=12345-123

Hi Smarsh,
It is shown in the browsers address line like this

When I make that request, I get a 301 redirect by WPML to the query string ending with a slash.
