This may not help but in your video it looked like the left hand side of the wireform was being hit by the upkicked ball and scrubbing momentum off the ball on the first (mainly) and second (not quite as much) try to kick the ball. The first failure looked quite obvious, seemed like the ball was hitting the lower left part of the wireform at the lower curve then rattling between the wires and falling after only going up about 2 inches or so. Maybe something to take a peek at / adjust slightly just in case the wireform is a bit off-kilter? The problem does seem to be more than just that but I thought I would mention it in case it helps in some way.
