Select a group and it will list the members of that group (it should be noted I do not have the option to select Interfaces at this point)
I then select a device and then interfaces and it will give me a list of interfaces under that device:
Next reselect the group and it will still stick on Interfaces, even though it is not a valid option in the initial screen. It should bounce back to Members at this point.
Release: 20.4
Component: Operator Console - Inventory
Fixed in CU7.
