Dup acks without Sack options

Hello , in the handshake , sack options is permitted by both sites. First i see a previous segment not captured and then a lot of dup acks. When i open the dup ack packets though there is not sack option which would show which sq number is lost. Why is that happening?

Hard to tell. Can you share the capture file or a screenshot of what you try to figure out?
