How do I change the settings for an absence that has already been created?

You can only partially edit an absence event with a fund once it has been created. In Settings / Absences, after clicking the desired absence, only the following items are editable:

name
note
whether the unused units are being transferred to the new year
event timeout for drawing
colour

You cannot edit ❌:

absence typ
time unit of drawing
annual fund
health reasons

Solution: if you have created an absence for vacations with an annual fund of 25 days and you would like to change this fund to 20 days for all users, you must create a new absence and deactivate the original one. The reason for this is to prevent unwanted changes to the data, which could be discarded after editing.

ATTENTION: Do not delete an unused absence completely, as this could also cause irreversible distortion of the data in the reports.

If you just want to change the size of the absence fund, an alternative solution is to enter the desired size of the absence fund in the Individual Fund column in Settings / Bulk Absence Settings.
