Hello,
Thanks for the URL. We have checked this out and yes this is weird as the settings are perfectly fine but the conflict is arising from the Revolution Slider. The issue here is since the Header used here is Transparent Header and the Revolution Slider's Slide is Dark, it is required to add the .dark Class to the Revolution Slider's Slide <li>:
<!-- SLIDE -->
<li class="dark" data-index="rs-689" data-transition="fadethroughdark" data-slotamount="default" data-easein="default" data-easeout="default" data-masterspeed="2000" data-thumb="include/rs-plugin/demos/assets/images/creative_bg1-100x50.jpg" data-rotate="0" data-saveperformance="off" data-title="Quality" data-param1="01" data-description="">
This will definitely fix the issue. Hope this Helps!
