Deleting non-working days should reschedule tasks (back to original length)

Hello everyone,

This might be a bug, not sure whether this is working as intended:

If I add non-working days to my personal calendar, my tasks automatically get rescheduled (if I take 5 days off, a 10-day task will require 15 days to complete). However, if I delete the non-working days, my tasks do not shrink back to their original size.

This breaks the whole feature for me. I need to be able to delete my vacation days without having to reschedule all my tasks manually.

Thank you very much for your help, kind regards,

Wiebke Willems
