I am trying to figure out why on my site, discounts are not showing how they are on others

[Mapple]

When I change the compare at price or anything to discount a product, it removes the original price on the home page, but when you go into the product, it shows, any ideas how I can show it on both?

 

Ideally on the first image it would like for it to show the 799.99 crossed out as well. But it does not show up?
