[Bug 1.64] Pump not putting water into cells.

I have a Miner with a pump set next to the Miner so I can extract water from the ground while the miner operates. I have the generator 10 or so blocks away, and a BatBox in the middle to intercept the power. I'm also using gold, insulated wires. The pump and miner all seem to be working. However, the pump won't put the water it has filled with into an empty cell. I'm putting the empty cells in the top slot, and I've also tried buckets. The only way I can seem to get this to work is if I wrench up the machine and place it down again so the water is emptied. I don't know what's wrong :(. I can't tell if it's me, or the machines. I'm doing this on my own server, which I've also tried restarting to see if it was server related.
