What correction are you seeking? Are you trying to get segment credit in order to (re-)qualify for elite status?
If you book a direct flight that is two take offs and landings with one flight number, the solution is just to manually book them as two separate flights. (Use multi-city search and this option will come up.)
This not only gets you the extra segment credit (or the "right" number of segment credits), but also makes it easier to nab upgrades. Remember that if you have booked both flights as a single direct flight, upgrade availability needs to exist on both segments or you won't have access to the seat. However, if you book two separate flight segments, you can get the upgrade on one and wait list the other.
