Hello,
Since there is a Pre-Defined Size of the Header, the Logo gets resized according that. Simply add the .header-size-custom Class to the #header Tag and then your applied Logo Size of 40px will work fine. Additionally, you will need to remove the .full-header Class from the #header Tag in order to remove the Borders. Simply consider using the following code:
<!-- Header
============================================= -->
<header id="header" class="transparent-header dark header-size-custom" data-sticky-class="not-dark">
<div id="header-wrap">
<div class="container-fluid px-4">
<div class="header-row">
<!-- Logo
============================================= -->
<div id="logo">
<a href="index.html" class="standard-logo" data-dark-logo="img/logo/white-logo.png"><img src="img/logo/color-logo.png" alt="Red Pine Logo"></a>
<a href="index.html" class="retina-logo" data-dark-logo="img/logo/white-logo.png"><img src="img/logo/color-logo.png" alt="Red Pine Logo"></a>
</div>
<div id="primary-menu-trigger">
<svg class="svg-trigger" viewBox="0 0 100 100"><path d="m 30,33 h 40 c 3.722839,0 7.5,3.126468 7.5,8.578427 0,5.451959 -2.727029,8.421573 -7.5,8.421573 h -20"></path><path d="m 30,50 h 40"></path><path d="m 70,67 h -40 c 0,0 -7.5,-0.802118 -7.5,-8.365747 0,-7.563629 7.5,-8.634253 7.5,-8.634253 h 20"></path></svg>
</div>
<!-- Primary Navigation
============================================= -->
<nav class="primary-menu">
<ul class="menu-container">
<li class="menu-item">
<a class="menu-link" href="#content" data-scrollto="#content" data-offset="0"><div>About Us</div></a>
</li>
<li class="menu-item">
<a class="menu-link" href="#form-section" data-scrollto="#form-section" data-offset="0"><div>Contact Us</div></a>
</li>
</ul>
</nav><!-- #primary-menu end -->
<form class="top-search-form" action="search.html" method="get">
<input type="text" name="q" class="form-control" value="" placeholder="Type & Hit Enter.." autocomplete="off">
</form>
</div>
</div>
</div>
<div class="header-wrap-clone"></div>
</header><!-- #header end -->
