Even if I take the time to enter passport details in the app/online, CX staff always rescan the passports at check-in, or, if you do online-check-in, they will do this at the gate before you're allowed to board the flight. The website even has a graphical note to say that it has been captured from a scanned passport vs just entered manually.

So I wouldn't worry about it very much, CX will fix it for you before they fly you, and before they presumably provide the "final" version to immigration authorities for "Who is on this plane".
