ASP.NET Formview некорректно обновляет базу данных SQL

У меня есть asp.net Formview, подключенный к источнику данных SQL. Когда я создаю/редактирую/удаляю запись, данные столбца стираются. Я уверен, что это просто неправильное кодирование, так как все, что я знаю о SQL/asp.net, было нагуглено за последние пару недель.

Вот код SQLDataSource.

 <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:hulc01ConnectionString %>"
    SelectCommand="SELECT * FROM [Common]"
    InsertCommand="INSERT INTO [Common] ([Project_Name], 
        [Business_Category], [Project_Description], [Operations_Owner]) 
        VALUES (@ProjectName, @BusinessCategory, @ProjectDescription, 
        @OperationsOwner)"
    DeleteCommand="DELETE FROM [Common] WHERE [ProjectKey] = @ProjectKey"
    UpdateCommand="UPDATE [Common] 
        SET 
        [Project_Name] = @ProjectName, 
        [Business_Category] = @BusinessCategory, 
        [Project_Description] = @ProjectDescription, 
        [Operations_Owner] = @OperationsOwner 
        WHERE ProjectKey=@ProjectKey" >
    <DeleteParameters>
        <asp:Parameter Name="ProjectKey" Type="Int32" />          
    </DeleteParameters>
    <UpdateParameters>
        <asp:Parameter Name="ProjectKey" Type="Int32" />            
        <asp:Parameter Name="ProjectName" Type="String" />
        <asp:Parameter Name="BusinessCategory" Type="String" />
        <asp:Parameter Name="ProjectDescription" Type="String" />
        <asp:Parameter Name="OperationsOwner" Type="String" />            
    </UpdateParameters>
    <InsertParameters>
        <asp:Parameter Name="ProjectName" Type="String" />
        <asp:Parameter Name="BusinessCategory" Type="String" />
        <asp:Parameter Name="ProjectDescription" Type="String" />
        <asp:Parameter Name="OperationsOwner" Type="String" />
    </InsertParameters>
</asp:SqlDataSource>

А вот код formview
