Why isn't a certain HUD icon showing on my profile?

On your profile, beneath your basic information, you will see small icons that indicate the HUDs that you own. But, these icons only show "additional" HUDs that you own, other than the HUD that represents your main race. The icon for your main race HUD is indicated in the upper right, in your main status icon.

For example, if you own both The Thirst and The Rage, and you are a vampire, your main status icon will be a vampire icon. Under your additional HUDs, you will see the icon for The Rage. If you were to change to a lycan, your main status icon would change to a lycan icon, and you would then see the icon for The Thirst under your additional HUDs.
