Bullseye! The weight context for passengers per regulation is based on age. The system has the birthdate and should label/populate the passenger element accordingly. Using "titles" is plonkers of a job at the SW definition phase, regional customs or language notwithstanding.
And the proper ones do. I ran once into an issue of an infant turned child between the check-in time and loadsheet closure. Partly for us being late and it has become a substantial headache on a full flight. Tirana in Albania it was.
As long as some are looking to point fingers, perhaps it's the business choice of TUI not to use proper industry-grade systems which deserves the attention. Or (to demand and pay for) proper aviation-style validation procedures, i.e. white-box testing.
