Navigation folder slug indexable but has no content page

Hi there. Does anyone know how to make a folder slug a page? For instance, if I add a Services folder to my nav, the slug is /services, but that slug is added to the sitemap and indexed by Google. However, when you visit the /services URL, there is no content, and it returns a 404 error page when I try to add a content page for the /services slug (so that the indexed /services URL has a page and content, I cannot because the folder name takes up the /services slug, I hope this makes sense.

What is your site url or which template do you use?
