The slider can only appear on two places, the “Front Page” and on the “Posts Page”. On your “mustangwrestling” site you have a static front page and a post page and both have the slider.
On “hoochwrestling” you say you want both the home page and the news page to display the Posts Page, is this right? I don’t think that’s possible since WordPress only allows you to set 1 page as the Posts Page. But you say you accomplished this earlier? If that’s the case then I really have no clue how you did that.
To make the slider appear on two areas. You have to set things the way you did on your other site. A static page for the home page and a different page to display the “posts page” aka “blog page”.
