I'm using WSL on Windows and found that almost every packet sent from Windows to WSL is retransmitted

Is this a case where, given that the packets are going between a host and guest on the same machine, NDIS treats the packet as first being sent on the interface and then as being received on the interface, so that it's delivered twice to the Npcap driver?
