Group Pricing by Item

I have installed this module and have a couple of issues, both in the Products Price Manager.

1. In order to add prices to an item, I press the Install button for Special Price Info. I can then add prices for the 4 groups.

However, after doing this, nothing in the Products Price Manager shows the prices that I have added. The prices do appear correctly on the site.

2. Further, a single Special Price Info appears. I suspect that the group prices should show here as well??

The Special Price is offered to people who are not logged in. So, if this is 0.00 they get the item for free.

I figured out #1 - I can use Catalog-->Specials.

But how do I disable the existing Special Prices option.
