2nd Articles containers shows wrong posts

Hello

I have a articles container in the top level of the site which has a number of blog posts and all work perfect, however I have now created a new Articles container also in the top level of the site the new Articles container shows in the menu fine but when this 2nd Articles container is viewed the posts that are displayed are of the 1st Articles container.
Had a look though all the obvious templates but cant see any setting to point this new Articles container to the correct set of posts.
Is anyone able to give me any clues.

Cheers
