Sitemap confusion…XML and Dagon

Hi guys
Not too sure what’s happening with my Sitemap and the plugin I use for my site https://www.spacessential.com
I use both XML Google map and Dagon sitemap. The way I understood it is that XML is really for SEO purposes, and Dagon is more for the user experience – providing a map of the entire site.
Now I’ve created a Sitempa page for Dagon following their instructions and putting the code in it – and when I go on it as you’ll see here https://www.spacessential.com/sitemap it actually looks like it’s the XML page, which is not very useful to a user!
Not sure what’s happening here and I’ll be grateful to receive your help on the matter, thanks!
