I have an instance that is after the July Update. After I change the Relationship Behavior from "Parental" to "Configurable Cascading" ,change the settings and click "save and close",
the "type of behavior" will be changed to system and I cannot change it to other types again.
I also tried to do the same action on the same entity and same relationship in other instance that is before July update, it worked fine in that instance.
