Posts added to Calendar when installed, cannot delete

I have installed Schedular with Wordpress. Calendar shows on required page.
174.120.151.190/~rrm/island-events/

Problem is content from previously added Posts have been added to the Calendar.

These Events are not showing in the Schedular Events Admin, I tried Reload.

I cannot edit any of the Calendar entries to delete them. The Edit feature does not show.

In fact I cannot Add an event either.

I have checked permissions for Add and Edit

I tested with TwentyTen theme to make sure it was not a theme issue. Same problem.

How do I delete the unwanted Calendar events and how do I Add new ones?

Thanks

It looks like option “Show blog posts as events” is turned on.
Try to uncheck this option in ‘Settings’ tab of admin panel.
