Pay attention to the differences between the following three selection methods. You can debug it yourself to see which one you are using. do not pour over all same net objects: only connect the pads of the same net, and do not connect other things such as copper and wires. pour over all same net objects: connect and cover all pads, wires and copper of the same net. pour over same net polygons only: only connect the pads and copper of the same net, and do not connect other things such as wires.
