Providers cannot be configured

Hi there,

I've encountered a strange issue with my project today. I was re-writing several elements of my support ticket application and I recreated the web.config file. Adding the providers back in, I find that I cannot seem to set them up properly using the ASP.NET Web Configuration Tool - according to the tool my providers don't exist, I only get the option to use the default ones. This is my web.config file:

<?xml version="1.0" encoding="utf-8"?><!--

            If you are deploying to a cloud environment that has multiple web server instances,
            you should change session state mode from "InProc" to "Custom". In addition,
            change the connection string named "DefaultConnection" to connect to an instance
            of SQL Server (including SQL Azure and SQL  Compact) instead of to SQL Server Express.

And this is what I see when I try to select them in the Tool:

I've probably borked something up somewhere, however I just can't seem to find the issue. Why can't the Tool 'see' the custom providers (so I can therefore set up roles etc)?
