Scheduler shows not all events

Hi,

i have sheduled 12 events from 9th march to 31th march.
The events are from 6am - 23pm - all works fine, but i only see _all_ sheduled layouts on the day, that the events was sheduled.
The calendar only shows the first three layouts and shows no the "+events" link on the other days (9,10,11,12...)
