Opening Menu Link in new tab (using Gleam theme)


I am using Gleam theme from elegant themes. I used custom links. I wanted to open the links in new tab. I set everything correctly in Appearance>Menu options.

But its not working

URL is gyansamar dot com
Apart from Home link other two are set to open in new window. Please check it. Notice the link in the browser after clicking registration link in the menu.

let me know how to solve this problem. Thanks
