Before submitting a new issue

• I tested using the latest version of the library, as the bug might be already fixed.
• I tested using a supported version of react native.
• I checked for possible duplicate issues, with possible answers.

We got the same issue here.
As a dirty workaround, we force the re-render of CalendarContainer in this specific case:

const key = useMemo(() => {
  if (Platform.OS === 'android' && numberOfDays === 1) {
    return 'android-single-day';
  }
  return 'default';
}, [numberOfDays]);

return (
  <CalendarContainer key={key} numberOfDays={numberOfDays} />
);
