Mine did that. I ditched it a long time ago so I do not remember the exact procedure, but there is a button sequence to hold down when you plug it in that puts the charger into a different mode. It will allow you to flash a different firmware to it which is what fixed mine. I had to go back to an old version. Mine started doing that when I was arrowing through the numbered storage slots. When I hit a certain one it flipped out and that was all she wrote. I had to reflash.
