GP Settings shown as "Extra Registry Settings"

Environment: Windows Server 2003 with XP Professional SP3 clients, Internet Explorer 8.

I've attached a screenshot from the settings tab of a Group Policy Object. This issue has been driving me mad for ages. As you should see, on the first page of the screenshot, I have some settings that actually relate to the Site to Zone mapping for Internet Explorer. For some reason, the settings are listed under Extra Registry Settings. I have tried adding what I thought were the correct adm files to the policy, but no joy in getting a better display in settings. Have i got two similar adm files that are cancelling each other out???

Second page of attached screenshot show the adm files for IE that I have.

Can anyone shed any light on what I need to do? It would be so much easier if the settings were displayed correctly, so i don't have to trawl through GP editor to find where I need to make changes.
