Lost all smelted bars

I was checking to see how much for a shipment I would have for smelted bars with dust so I put it into a shipment and selected a port. It wasn't as much as I wanted to I deselected the port and shipped out some plants. When I rechecked, all my smelted ores were gone. I probably did something dumb but I can't figure out where my smelted ore went. It says 0 accross the board and I can't figure out how to get the smelted ore back
