current_query_markers

When I do this shortcode in the sidebar: [travelers-map current_query_markers=true height=200px] it loads markers for all of the posts in the site, not just the ones on this page. On single posts, it just shows the one, but on archive pages (like the most recent homepage) it shows every marker in the database.

I am using the a theme by Themify and wondered if that was the problem, but when I switch over to Twenty-TwentyOne it does the same.

The page I need help with: [log in to see the link]
