Doesn´t respect the date

Hello averybody.

I would like to help me to use to how could I insert the correct date because for example :

I want to choise the task start day 03/06/2021 and task end day 06/06/2021 and give accept and doesn´t save the changes.

You defined 6 days out of 7 in the week as weekend days in your project. By default weekend days are not working and tasks can’t start or finish on weekend days.


Now it works fine.
