Error in printing mathml

I am creating a website for mathematics tutorials and obviously I need support of mathml but when I print a solution written in Mathml browser shows a strange error, I don't even know if it is an error. I am using ckeditor in admin panel to enter the same mathml.

    <div class="container">
        <h2>Solution</h2>
        <div class="panel panel-default">
            <div class="panel-body">
                <asp:Label ID="lblSolution" runat="server" Text=""></asp:Label>
            </div>
        </div>
    </div>

In above lblSolution I am assigning the mathml from back-end as received from database.

Here is the screen shot of the output I am having.
