When adding a holiday in the schedules list it will only show once.
However, when you click save you do not get any feedback wether or not it has been saved.
After reloading the screen the holidays are added twice.
After removing all the double holidays this is fixed.
I'm no longer able to reproduce this, but now can no longer add new holidays. (Christmas 2024)
Is there a cap of the amount of holidays you can add in the schedule?
