Can't delete lists in beta

when I click the “Remove this list” from the … button it generates " Whoops! Unfortunately, we could not find the page you’ve requested."

when I try to do this in v2, we go to https://www.icheckmovies.com/lists/remove/working/ which asks " Are you sure you want to remove your LISTTITLE) top list?" (which generates an iCM is down message)
