In wireshark, each conversation entries are grouped together. It is displayed in the first column[No.] with a connecting line. From the image that you have shared, it seems like all these packets are part of the same conversation. You can right click on any of the entry and follow the TCP stream.
If you have multiple conversations, then try the following.
View Conversations: Statistics -> Conversations -> TCP (tab). Then select one conversation (based on your source/destination) and click on 'Follow Stream'. That will create a display filter to show only that single conversation.
You can also display filter manually: tcp.stream eq 0 or tcp.stream eq 1 etc.
