Two lists on the page. Events and Contacts.

1. Use the Change Filter on the Events List to Filter for an Event.
2. Use the Change Filter on the Contact List to Filter for a Contact.
3. Use the Change Filter on the Events List to Filter for "All".
4. Use the Change Filter on the Contact List to Filter for a Contact.
And the Events Lists reverts back to The Filtered view NOT "All".

How can I stop this?
