Not capturing traffic on both Egress and Ingress interfaces question

[CiscoBrownBelt]

So I have an issue with a server and host failing on the SYN/ACK (server replies to SYN, however host never receives the SYN/ACK). I only always capture traffic on either the Ingress or Egress interace but not both when just filtering using the host IP. Would this just be because there is no full 3-way handshake traffic as I usually don't change source or destination IPs when setting up a packet capture filter - I use the same IPs for both ingress and egress interfaces that I want to capture traffic on.

If you use the packet capture wizard in ASDM it will create both capin and capout captures and show you the traffic on both ingress and egress sides of the firewall.

That's what I use but for some strange reason it is never showing anything for both interfaces. I leave the source subnet to capture let's say 10.10.10.0 255.255.255.0 and destination 0.0.0.0 for both ingress and egress. Only when I just swap the ingress and egress interfaces, it will show the data on the other interface that was not shown, but now not the other. Strange. I am also positive that those are the proper interfaces the traffic is routed.
