There is a bug in the theme. The dashicon in the campaign tab is returning an http url i.e. https://dashicons%20dashicons-megaphone/. I have changed the code at /CP9/framework/new_class/ppt.php from ‘menu_icon’ => “dashicons dashicons-megaphone” to ‘menu_icon’ => “dashicons-megaphone” and the problem solved. This url caused an insecure URL of my site and also the dashicon was missing from my admin navigation menu. I found this bug on this directory theme, coupon theme and dating theme as well.
