I have been successfully using your product for many years. The new website interface is confusing. I want the last modified date to appear next to the all files in my sitemaps. If I create a XML sitemap using your free product and the website has less than 50 pages, the date appears in the sitemap where I want it to. I have one website with 320 pages. When I run your free sitemap generator on this website, the date does not appear even if the files have recently been modified. How do I get the last modified date to appear on the 320 page website? Thank you.
