User Group Pricing Issues V4.0.1

I noticed an issue in v 4.0.1. I set up a user group that will get 50% off of our retail pricing for candles. In Doc1, you will see the listing of our items under the category shows the regular price. When you go to Doc2, you will see when I clicked on one of the items to show more detail. The correct pricing is showing under the product detail, but the wrong price is showing up under the category listing. Does anyone know how to correct this. It is confusing my customers. Thanks for any help!
