Modx 2 creating child on a protected resource

It seems that, there is some behavior in modx 2 which works kind of odd.
With a resource assigned to resource group, user will need to have 2 different policies under user group to be able to create child under the protected resource.

+ Resource group: "your resource group name", min role: "Member", Access policies: "Administrator", Context: "mgr"
+ Resource group: "your resource group name", min role: "Member", Access policies: "Resource<", Context: "mgr"

Hope it helps for ya ;)
Cheers~
