Members page

I just noticed that there’s a page called members, I’m guessing that’s where you can see the people/members of my site, I don’t really understand what’s up with page or how to configure it, this the link to the page https://movimixx.com/members/
Pls do check it out and perhaps what I should do

I feel that page was supposed to show all registered member on my site, but instead it was showing an unknown code more like a 1 line HTML code in the page, so I had to trash the page so it would show that 404 page instead of that one line code making it look more professional, so I was saying if the page was actually just supposed to show the members in my site or I had to do something first to be able to make the page work or function the way the members page is supposed to function

Honestly, I first didn’t see it in the pages section, then I saw it automatically appear, or perhaps it’s a plugin I downloaded that automatically brought out that page, does something like that happen? You download a plugin and then a page automatically appears?, if not I’ll try and see to delete the page since it’s not in the demo at all, cause it’s showing in chrome if I search Movimixx(my site) and states besides it that it’s because I visit the site regularly and I registered to the webite
