Move it down with top... just add the top here:

.dropdown-content {
    top: 45px;
}

OR, add the dropdown-content inside the dropbtn - now they are not inside, but right after - eg:

<div class="dropdown">
    <button class="dropbtn">
        <i class="fa fa-caret-down"></i>
    </button>

    <div class="dropdown-content">
    </div>        
 </div>
