I had tried that several times the night before last with no luck but last night after a bit voila I heard a snap and here came the ball.
The ball had got stuck in the spring causing it to wedge back in the channel. This may help others having trouble filling their (I had trouble with this one). I had taken everything apart the night before and pulled one ball out after the screw and donut ring. I just thought that there was suppose to be two of them.
But when I went to put it back together last night I thought that that doesn't make sense so I put together just using one and now the thing works great.
Hindsight what caused the problem was it having two instead of one causing the one to get pushed to far in the channel and wedging in the spring.
Anyway, now none of my mechs have to be without a topper.
