website not updating when backend is saved and showing new version

Site URL: https://www.humlondon.com/contact

I have updated a page on my website and saved it via Squarespace. however the updated version is not showing when the website is seen by others. have done other updates  on other pages that have worked but this one just isn’t showing up to other people.

Please post a screenshot of what you are seeing in the editor so we can compare.
