Kaptinlin Themes Support

Hi, I'm styling main navigation menu right now on this website http://christianedu.org/; however, sub-menu style of <ul> was hardcoded as shown on the screenshot with this values:


<ul class="sub-menu" style="top: 60px; display: none; visibility: visible; ">


Unfortunately, I cannot find the file where this values were added. Can you, please, help me to find this file, so I can change this values?
