I am not clear - but will try to respond based on the following assumptions;
All three Policy Servers are used to administer a common Policy Store
There is only one (1) AdminUI instance, which may reside on any platform
The Administration UserIDs are not Internal accounts, rather they are External (i.e. stored in the User Store)
The AdminUI was registered (XPSRegClient) for all Policy Servers - if not - this could cause this behavior
NOTE: "Best Practice" is to assure all administration actions are performed on a common server.
e.g. For PS-1, PS-2, PS-3 - administrators should only use PS-1 for administration changes
There have been cases of when making changes on different policy servers, this can result in phantom objects.
Hope this helps,
