As per the screenshot there is SYN-ACK and corresponding (5 and 6) and finally client sent an ACK (11 and 12)
so the server listening on port 2048 , is'nt it ?

A couple things could help clear it up if you can repost the screenshot:
It looks like we see two sets of three-way handshakes here, both on destination port 2048. Both handshakes are complete, and there seems to be an exchange of data (client sends PSH flags on frames 11-12, 13-14, and 15-16; the server sends a reply in frames 17-18).
If the traffic is known to Wireshark, you can also decode it as the known traffic (if it's TLS for example, right-click on any frame and choose Decode As..., and specify port 2048 to be whatever the actual traffic is).

Yes, correct. The server is listening on TCP 2048 port (no doubt) but same time we can see SSL traffic to the same server. But what l am trying to understand is how is the PA seeing this traffic and how it is identifying? Under which application. This all info is under Monitoring tab on PA.

@TranceforLife is bringing up a really good point. If the only information that your giving is a wireshark it doesn't actually tell us what the Palo Alto itself is seeing. Knowing what your security policy for the traffic looks like, how the Palo Alto is seeing the termination, all of that other good information.
