Security Parameter problem

Hi I use a Domino 8.5FP1

When I apply a new created security parameter document in a policy document, I have this error message in console :

14/08/2009 14:05:49 Problem with signature on policy document /PolicyName or one of the policy setting documents it specifies: Document has been modified or corrupted since signed! (data)

Same message when I try extract a synopsis policy of an user.

This problem is just with parameter security which I have created or modified.

For the security parameter doc, created by IDVault wizard, there are no problem until I modify it.
