[Solved] One table not updated using VB 2010 Express and SQL Server 2008 Express DB

I have a Managers table and a Dealership table in my SQL Server 2008 Express Database. (I'm new to SQL Server)

I am using the code below to update the dataset. Changes to the Dealership table are not being reflected in the dataset. They show immediately after the update, but if I close the project and reopen the project, the changes are missing. Changes to the Manager file are reflected just fine.

I just noticed that my TableAdapterManager says "ManagersTableTableAdapter" in properties and there is no TableAdapterManager for the DealershipTable.
Is this OK or not?

What could cause this??
