Adding References cannot occur to VB.NET Deseleting the references once added

[TnTinMN]

I've obviously overlooked something in my project rebuilding. I had to port my VB.NET 2013 Express project to another PC and so I'm am reconstructing the environment. I've been fighting getting the references to not be deselected. Every time I go back into the Project -> Add Reference -> Assemblies -> Extensions screen I check the components I need and click OK to save my selections. When I reopen the screen, the components are no longer checked. I appear to be getting rejected, but I don't know why.

I tried what I thought was the equivalent thing by using the Solution Explorer to select from the References and note that the components I need have their warning signs active. ...

Have you tried first deleting the references in the Solution Explorer that have the warning icon before you try to add the reference again?
