Problem With Access Levels

I am having problem with Access Levels and URL Groups.

I can have a single URL Group selected in Access Levels and only those URL works, but once I select multiple URL Groups in Access Level, I do not have permission to access anything.

eg.
URL Group List 1 = yahoo.com
URL Group List 2 = google.com

Access Level have List 1 checked, only yahoo.com works.

Access Level have List 2 checked, only google.com works.

Access Level have List 1 and List 2 checked, neither yahoo.com or google.com works.
