Split-screen character selection with keyboard and one gamepad focus problem

I’m basically trying to create Mortal Kombat like character selection menu for my split-screen mode and the problem that my 0 controller (keyboard) and 1 controller (gamepad) are sharing the same focus in my 3D menu… it means I can pick a character only for my 0 controller using both gamepad and keyboard (Skip assigning gamepad… is set to true). Any idea how to fix that? Maybe I’m missing something… I’ve spent already one week trying to resolve this, I really hope someone can help me.
