Nevermind I managed to resolve it alone.
For anyone wondering just copy this code inside the Custom CSS Box:
.top-title-wrapper { background-color: #ffffff; width: 100%; overflow: hidden; -webkit-box-shadow: inset 0px -2px 3px rgba(255, 255, 255, 1); -moz-box-shadow: inset 0px -2px 3px rgba(255, 255, 255, 1); box-shadow: inset 0px -2px 3px rgba(255, 255, 255, 1); border-bottom: 3px solid #ffffff; }
In this way you replace the background color to white and the white title is simply invisible. Obviously if you changed the background color you should adjust the values to match it. So insert your background color instead of white (#ffffff) (rgba(255, 255, 255, 1);)
