yoast XML plugin not showing articles in Google

I am using yoast xml for my posts to be included in Google but there seems to be a problem. Yoast is publishing pages, but there are pages that i dont want in google. But, it is not publishing any of my posts in Google.

When I put in site:headlineplus.com it should show all my articles but not a single article or post is showing. can anyone give me advice please
