Visual Studio Bug? Adding a dataset parameter doesn't add a report parameter in Visual Studio 2008 SSRS

Hello,

I apologize if this isn't in the right forum, however when using Visual Studio BIDs 2008 to create SSRS reports, I keep running into an issue.  I'll go to a dataset, open up the query designer, add a new parameter, then refresh the fields, but the parameter won't be added as a report parameter.  If I go to the dataset properties under the list of parameters, the value in the dropdown will be blank.  However, sometimes this will automatically add. 


Is this a bug in Visual Studio?  How do I get around this?
