Policy Disappears

I am experiencing new policies disappearing from the NAB. We have mainly 7.0.2 servers and have brought up a new 8.0.2 server. The NAB design is now at 8.0.2. I’ve created an explicit policy with a mail policy to add a disclaimer and a desktop policy to set internet mail to Notes Rich Text. I can apply the policy but in a day or 2 the policy has disappeared! I have recreated the policies with different names with the same result. Help! (will this be resolved with all servers on 8??)
