Hi, i have the same problem:
for example i have one event:
holidays from july 30. - september 12.
which is showing in july, august but not in september.
i created another event to test this: holidays from march 19. - may 16.
which is showing in march, but not showing in april and may.
Is there a chance that an update is coming soon?
Thanks for the workarround-suggestion. There is one problem with it: If i create multiple events they will show multiple times for example in the list-view.
Despite this problem WP FullCalendar is working fine!
