I would start by recommending that you allow the login form to display in place of blocked content (enabled under Options > Content > Show login form).
Your link in your menu to “fast track” takes the user to the login page, and direct linking to the page makes the user go to the login page. It’s more complicated than it needs to be.
Are you blocking/requiring login on more than that single page? It doesn’t look like you do, in which case adding a separate login page is not really necessary.
If it’s just the one page, you can just add a logout link directly using the [wpmem_logout] shortcode (see: https://rocketgeek.com/plugins/wp-members/docs/shortcodes/other-shortcodes/).
If you’ve got more pages, then a separate login page makes sense, in which case you could add a login/logout menu item. See: https://rocketgeek.com/plugins/wp-members/docs/menus/login-logout-menu-link/
