WFP: Getting same incoming packet for FWPS_LAYER_DATAGRAM_DATA_V4 Classify callback on port 53

I have registered FWPS_LAYER_DATAGRAM_DATA_V4 callout.
In classify callback, I am parsing incoming traffic on port 53 but gets 2 same incoming packets.
Environment: Windows 10 64 1803

Does anyone observe the same kind of issue?
