Those are generated fields created by Wireshark when the capture is read in.
doc/README.dissector:
proto_item_set_generated()
--------------------------
proto_item_set_generated is used to mark fields as not being read from the
captured data directly, but inferred from one or more values.
They are set in packet-tcp.c
/* encapsulate all proto_tree_add_xxx in ifs so we only print what
data we actually have */
if(ta->frame_acked) {
item = proto_tree_add_uint(tree, hf_tcp_analysis_acks_frame,
tvb, 0, 0, ta->frame_acked);
proto_item_set_generated(item);
/* only display RTT if we actually have something we are acking */
if( ta->ts.secs || ta->ts.nsecs ) {
item = proto_tree_add_time(tree, hf_tcp_analysis_ack_rtt,
tvb, 0, 0, &ta->ts);
proto_item_set_generated(item);
}
}
