Laravel clicking on link adds to url

Okay I have a small problem.

When user clicks on a link it goes to website/create/business which is fine however if nothing is done but the link is clicked again, it goes to website/create/business/create/business for whatever reason.

<li class="dropdown">
                        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">
                                     <span class="caret"></span>
                                </a>
                        <ul class="dropdown-menu" role="menu">
                            <li>
                                <a href="profile/">Profile</a>
                                <a href="create/business/">Add Business</a>
                                <a href="" onclick="event.preventDefault();
                                                     document.getElementById('logout-form').submit();">
                                    Logout
                                    </a>
                                    <form id="logout-form" <a href="" action="" method="POST" style="display: none;">
                                        
                                    </form>
                            </li>
                        </ul>
                    </li>
