PcapNg vs Pcap Import

[ShinyProphet]

I am noticing an issue of seeing a significantly different network when importing the same packet capture, saved as a .pcap and then as a .pcapng. I have tried several packet captures with the same results. The live capture is being done with Wireshark and being saved originally as .pcapng and then later converting it to a .pcap. The .pcap file import shows significantly more information versus the .pcapng.

Any thoughts? Thanks.
