I don't know how do you monitor ARP packet but I think what you see is correct. Here are the reasons:
First, you ARP request packet will be broadcast to LAN by switches. Your computer only needs to send one ARP request packet and the broadcast is done by switches. So the monitor shows your ARP request packet as an indication for this step.
Second, the gateway router sent the ARP reply packet to you (unicast because the switch is self-learning) by the switches. So the monitor only shows ARP reply packet from the gateway router as the indication for this step.
