We'll create fresh WordPress site with Post Type Archive Link installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Post Type Archive Link creates a metabox on the Appearance > Menu admin page.
This lists your custom post types and allows you to add links to each archive page in your WordPress menus.
The plug-in uses WordPress’ default menu classes for current pages, current page parent and current page ancestor.
By default all post types with archives (and not registered by core) are available for adding to your menu.
You can forcibly revent a particlar post type from appearing using the show_{$posttype}_archive_in_nav_menus
hook.
