Default [Q] Sony Xperia M Data Traffic opens up Phone in background.

Guys I need some help, I bought a Sony Xperia M last week. And I just noticed that Whenever I turn on the data traffic from the navigation pane (ALL THE RECENT APPS LIST WAS EMPTY AT THAT MOMENT) after that I noticed that the "Phone" app is in the recent Apps list. And when I tap on that It disables Data Traffic and when I press it again It turns back Data Traffic back On. I don't understand. It's so annoying and is there a way to get rid of it? Thanks in advance
