Menu messed up

Hi there,

When events page displayed for some reason entire list of pages are showing up at the menu – not the main menu item.

This seems to be a bug –

Oe work around I found is creating a events page separately but “view all events” link still show up at the top, and take people to the messed up menu page.

Is there a way to link all events page to a different page?
or is terse another way to solve this problem?

you can see the problem at this link http://www.healingthewoundsofhistory.org/events/

thank you.
