Listable Log In With Ajax Error

I am experiencing and issue for https://www.travelafrique.com when trying to call up the LOG-IN with AJAX modal popup box.

I’d like to prompt users to log in via a button on the specified page above and another one page….I WANT to get the same log in box that pops up when I click Log-In in the menu…but instead the page reloads and brings me to WordPress log in page….

-I have added a button to this page too: https://www.travelafrique.com/photo-blog-from-africa/

1) See screen shot of button: https://www.dropbox.com/s/rl9k34k73iwy6yi/Button%20Example.png?dl=0

-This button goes to URL: https://www.travelafrique.com/wp-login.php
-And has a class of : vc_btn3-container lwa-links-modal lwa-login-link vc_btn3-center

But I am NOT getting the right POPUP modal box that I want – I am getting directed to a different WP page. I also have the [lwa] shortcode on the page.

2) Screen shot of the POP UP I WANT: https://www.dropbox.com/s/a3wrexrogisp7gw/Login%20MOdal.png?dl=0

3) Screen shot of what I get instead: https://www.dropbox.com/s/j1mtw6fzibwnfbj/Bad%20Login.png?dl=0

?? How can I get #2 instead of #3 to appear when I click the button??
Thank you. Please advise.
