Two Menus gives me message “Text Duplicate”

My website has 2 menus: 1 is used for mobile devices and the other for desktop devices. When I test my SEO in "Seobility.net" I get the message "Text Duplicate". (Image attached) Is there anything I can do to indicate to the spider that one menu is for mobile and one is for the desktop? The mobile menu is located at top right of the website whereas the desktop menu is located at the side. Here is the code:

<nav id="main-nav" class="h-nav">           <div id="show-nav"><a href="#">Menu ☰</a></div>           <ul class="nav-menu">             <li><a href="https://www.tranquilhavens.com.au" class="current">Home</a></li>             <li><a href="dwarfmondo.html">Dwarf Mondo Grass</a></li>             <li><a href="dwarfmondotrays.html">Dwarf Mondo Trays</a></li>             <li><a href="koreangrass.html">Zoysia No Mow Pots</a></li>             <li><a href="nomowgrasstrays.html">Zoysia No Mow Trays</a></li>             <li><a href="dichondratrays.html">Dichondra Trays</a></li>             <li><a href="thymemagiccarpettrays.html">Thyme Trays</a></li>             <li><a href="corsicanminttrays.html">Corsican Mint Trays</a></li>             <li><a href="zoysiaexperiment.html">Zoysia Experiment</a></li>             <li><a href="contactus.html">Contact Us</a></li>             <li><a href="links.html">Links</a></li>           </ul>         </nav>         <!-- END: header -->         <div class="main clearfix">           <div class="sidebar">             <ul>               <li><a href="https://www.tranquilhavens.com.au" class="current">Home</a></li>               <li><a href="dwarfmondo.html">Dwarf Mondo Grass</a></li>               <li><a href="dwarfmondotrays.html">Dwarf Mondo Trays</a></li>               <li><a href="koreangrass.html">Zoysia No Mow Pots</a></li>               <li><a href="nomowgrasstrays.html">Zoysia No Mow Trays</a></li>               <li><a href="dichondratrays.html">Dichondra Trays</a></li>               <li><a href="thymemagiccarpettrays.html">Thyme Trays</a></li>               <li><a href="corsicanminttrays.html">Corsican Mint Trays</a></li>               <li><a href="zoysiaexperiment.html">Zoysia Experiment</a></li>               <li><a href="contactus.html">Contact Us</a></li>               <li><a href="links.html">Links</a></li>             </ul>           </div>           <!-- END: sidebar -->
