both in the 'design' tab and in the 'starter' tab, when I am adding the yeast to the recipe, I type the package date, and when confirming the inclusion, this date is modified to the current date, causing divergence in viability. The only way to fix the bug is to edit the yeast, after inclusion, and change the package date again. However, when yeast is added by clicking 'add yeast without closing the window', the typed package date is included correctly.
