Home page displays everything in the site

Hi, I have a site in Swedish with several pages, and I have translated the home page to English. When I display it using the URL https://localhost/wordpress/en/home it looks fine, but when I click on the English flag in the menu the URL becomes https://localhost/wordpress/en/, and then the home page in English is displayed, followed by the contents of all the other pages in Swedish. Only the home page is translateed so far.

I have created the English home page with the plugin Duplicate Page, then changed the text to English, and I am using Divi for the site. I have tried all the different settings in Polylang, but to no avail. The home pages are both titled Start, and the permalinks are start and home respectively.

What, if anything, am I doing wrong?
