You should file a ticket with Support on this issue. I have seen this behavior also.
If you want, you can private-message me with your Grant number and I can open a ticket for you and collect data from you. Or simply call in at 1-800-700-8238 (options 1, 1) to open a ticket over the phone.
In talking with support the issue was I was not forcing users to authenticate on the rule once this was done the problem did not exist
