More than 10 past events

I try to list all past events on my Events page with the following code:

[events_list scope=”past” order=”DESC” orderby=”event_start_date”]#_EVENTDATES – #_EVENTLINK, #_LOCATIONNAME<br>[/events_list]

But i get only 10 past events instead of all.
There are more than 10 past events in the database.

The page I need help with: [log in to see the link]
