I was checking my 2025 flight hours and Total Day is incorrect. When I create a New flight I specify Total duration and Night duration if concerned, never Day duration but in the settings I have selected Day duration as « Set day duration to total duration minus night duration ».

When I export CSV file and check Day duration with the day duration as total duration minus night duration and a sum formula, my day duration over the year is correct so i think the problem is in the app.

2 screenshots attached, you may see Day duration is’nt total minus night.

I have checked my 2025 flights, they are filled correctly (no day duration specified).

Thanks,
