I'm checked-in and have got a fresh new passport - so pretty sure there is nothing to worry about here and will chalk it down as another BA glitch.
I think that is a well known glitch when you had your old passport in there when booking. Updating to the new details doesn't seem to unlock the system but you'll be fine at airport
