Background of the issue:
I am trying to have a normal permalink structure. Currently, my main language products have URLs like hidden link, which is weird because it should just be called /product/. For the English website, the URL is hidden link. I want the structure to be /en/ for English and nothing for the main language Dutch. The issue can be seen at hidden link.
Symptoms:
The main language products have a permalink structure with /product-nl/ instead of just /product/. The English website has the correct structure with /en/product/.
Questions:
How do I get the permalink structure to be /en/ for English and nothing for the main language Dutch?
