Thanks, I checked and the issue is that you set the other pages for eh EN US contact page as a duplicate post.
That is why WPML tries to use the original content.
Please go to the edit screen of the contact page. From the top admin bar change the language to EN UK.
Click the Translate Independently and then it should work.
Also please consider that puc an manually add the canonical URL to EN UK by expanding the advanced settings in YOAST options on the page and see the Canonical URL
