What controls these two icons?

Okay. So in Thread Display Options (showthread) in AdminCP, there is:

Check Thread Subscription

If enabled, this option will notify the user that they are subscribed to a thread by displaying a small icon when viewing forumdisplay and search results. It will also change the "Subscribe to this thread" text on showthread to "Unsubscribe from this thread".

"this option will notify the user that they are subscribed to a thread". But in my case, as stated above, I am not subscribed to any threads anywhere within our forum. I used to, but I haven't had any for a long time, so why are the icons present. The attachment shows My Subscriptions under my Settings.
