Bootstrap Nav - 关于白点的CSS问题

Question

我有以下使用Bootstrap，以及它在现实生活中的外观图像：

       <div class="collapse navbar-collapse navbar-left">
            <ul class="nav navbar-nav">
                <li class=""><a href="/Analyst">Analysts</a></li>
                <li class="dropdown">
                    <a class="dropdown-toggle" data-toggle="dropdown" href="#">Coverage<span class="caret"></span></a>
                    <ul class="dropdown-menu" id="mynavlist">
                        <li><a href="/Coverage/AddCoverageSearch">Add Coverage</a></li>
                        <li><a href="/Coverage/Coverage?status=A">All Coverage</a></li>
                        <li id="mycov"><a href="/Coverage/MyCoverage?status=A">My Coverage</a></li>
                        <li class="addborder"><a href=""></a></li>
                        <li><a href="/Coverage/CoverageAssignments?groupingBySector=True">Coverage Assignments</a></li>
                        <li><a href="/Holding/PortfolioCoverage">Portfolio Coverage</a></li>
                        <li><a href="/Holding/PortfolioSnapshot">Portfolio Snapshot</a></li>
                                <li><a href="/Writeup/WriteupSections/34?status=A">Writeup Sections</a></li>

                    </ul>
                </li>
                <li><a href="/Holding/List">Funds</a></li>
                <li><a href="/Blotter/Account?analystname=Aaron%20Wasserman">Intraday Orders</a></li>
                <li><a href="#" class="dropdown-toggle">Reports</a></li>
            </ul>
        </div>

如果仔细观察，可以看到下面有4个小白点＆＃34;分析师＆＃34;，＆＃34;覆盖＆＃34;，＆＃34;基金＆＃34;和＆＃34;日内订单＆ ＃34 ;.它们是什么，我如何摆脱它们？
