I wouldn't be too concerned. Many people have multiple passports. Many more people incorrectly enter passport details. There are plenty of ways for agents to update this, if nothing else, when you arrive at the airport. If you want some peace of mind you can still try calling in advance but this should be easily sorted at the check in counter.
