We have identified an issue in Collection-Master 9.1D.006 that pushed notes to all linked claims, even if the check box “Push note to # claims linked by Report File?” is left unchecked. The solution will be available in Collection-Master 9.1D.007.
If you want to stop the behavior before installing the update, you can use the following workaround.
Navigate to [4-1-S-3] Group Security
In the *** Everyone Group, add the policy MAST PUSH LINK NOTES
