Not able to get all events - first is missing

[jules1091]

If I try to get all my events with the following code
{% set entries = craft.calendarize.between('2020-01-01', '2020-12-31', { section: ['events'] }, 'asc') %}
i only get the occurences without the next occurence on 4.4.

Is it possible to get a list with really all occurences including the first one with one query?

Thanks for your help!
