I had to click on the above images to see what you are talking about, for some reason the above are the same image until I did that.
Anyway, you noted the phone is rooted but didn't answer if you are using a custom/non-stock ROM or Android OS image. Just as every phone is usually different from one another so is every ROM. As my phone is using a custom ROM that is based on a few populare ROMs, like Cyanogen 10.1, this means that the app for contacts/people will be the same as quite a few other ROMs and I can see if it's a changeable feature or option.
If it's not a custom ROM you should search for a forum that supports the HTC Wildfire and ask there. If it IS a custom ROM you should go to the developer's forum/site and ask there.
Another good place to find information and support for the HTC Wildfire is "http://forum.xda-developers.com/forumdisplay.php?f=1035"
Let me know if that helped out at all.
