Path of "Add New Project" dialog strange behavior

I'm experiencing a strange behavior with the "Add New Project" dialog in a Visual Studio Shell Customization.

My solution can have two kinds of projects, lets call it A and B.

I fire up the Shell, then open one already-created solution that contains an A project.

Select File -> Add -> New Project... Select project kind B. The path listed points to a folderabove the solution folder.

Click OK, the project B is created. I remove it from the solution.

Select again File -> Add -> New Project. Now the path is listed correctly asbelow the solution folder.

Is there anything I could do to fix this?
