Wireshark noticed Error always when pcap file captured from wireless diagnostics app in MacBook Pro is opened

edit

I am using MacBook Pro 13 inch Touch Id model with High Sierra. I captured 802.11 packets with Sniffer in Wireless Diagnostics App preinstalled in MacBook. Then, captured data was opened by Wireshark (v2.4.4). However Wireshark said captured data was broken, it noticed "the captured file appears to have been cut short in the middle of a packet". I can see many beacon and probe response packets as broken. I tried several times, but always many packets are broken. Wireshark isn't compatible with pcap files captured for MacBook Pro with High Sierra OS ? Thanks.
