Absence Overview Settings
In the tab "Overview absences" (in the app settings under Admin, Absence management) you have the option to activate or deactivate. Once the slider is activated, the absences will be named in the calendar, e.g. sickness or vacation. This depends on how the absence accounts have been named. If the slider is disabled, it will be shown that an absence exists. However, the absence is not named with e.g. illness or vacation.
