theme Lensa custom links not appearing in menu

Hi, Am trying to develope a site using the Lensa theme, my problem is that the custom links not appearing in menu, only the pages, even the custom homepage link does not appear, and in the view source they are also missing, plus using developer tools they also do not appear. Does this theme not support custom links and is there a work around that i can use that they become visible in style.css or functions.php…
Thank you in advance
Melanie
