My Dilema

I googled these errors but can't seem to figure out why I encounter them on my development side as shown in my image below but when I debug and run the project they show up and work fine. The Role Manager is also enable in my web.config file too.  Any help experts?
<roleManager enabled="true">
      <providers>
        <clear />
        <add connectionStringName="ApplicationServices" applicationName="/" name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" />
        <add applicationName="/" name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" />
      </providers>
    </roleManager> ...
