After hitting escape and entering the swap hero menu, i noticed that when you hit "B" to open the build menu you get this weird outcome. Then I noticed you can just type anything you want and it will show up on screen.
It's actualy a filter for heroes. That's why you can type. If you type just 'B' you will have Bebop highlighted from hero selection menu. It's not a bug, but rather a feature. It will make more sense when the hero pool will be larger.
