Posts picking up random slides not the one selected on the Post or Page

WordPress setup : 3.5 multisite

Posts or Pages just pick up random slides not the one we selected on the Post or Page.
For all the slides we created we have selected the 'Not in Pool' option.
And selected specific slides in the posts. But this did not work on this site.
For now we have removed the other slides and have kept a generic slide. But are looking for a resolution for this issue.
