CPF's Application Monitor problem

If I add some application rule to AM with “Skip Parent” checked and than launch this application, CPF shows alert window and asks me if I want to allow or block this program.
Then in the AM rules, rule for this application changes (not adds). A “Parent Application” setting changes from “Skip Parent” to “Specify a parent”.

CPF v.2.3.4 (2.3.0.44)
