Actor-SwitchActor hierarchy combination issues

I have a hieararchy of actors and switch actors. The selection works fine when a switch actor is an immediate child of a parent switch actor(SwitchActor->SwitchActor). But when the hierarchy looks like this SwitchActor->Actor->SwitchActor, the switch selection at the root level turns on all the option on the child switch actor.
Selection works fine
SwitchActor
–SwitchActor
–SwitchActor

Resets the sub switch actors
SwitchActor
–Actor
----SwitchActor
–Actor
----SwitchActor

(Indentation indicates parent-child relationship)

Hi,
is there an update after 3 years of this issue?
I need to have this worked, like the tutorials suggest, for a car configurator.
Maybe EPIC devs are not that much into car development, but nested switches are common scenarios.

I am on Version 5.3, maybe newer version has fixed this problem?
