I see only HTTP/1.1 200 OK

Suddenly my wireshark is only showing packets from Source IP to Destination IP only. e.g. My source IP is 10.10.23.234 and destination IP is 10.10.23.236. Then my wiereshark should show packets originating from Source and Destination IP but instead it is only showing one direction responses. It is not showing request packets.

What went wrong with wireshark suddenly? Appreciate any help.
