Overridden editable in inheriting class cannot be assigned

Summary

If a concrete class inherits from an abstract base class, and uses the <override> specifier for an editable, that editable does not show up in UEFN, and can thus not be assigned.

Steps to Reproduce

Build this code, and have a look in UEFN - the TriggerDevice editable does not show up:

using { /Fortnite.com/Devices }
using { /Verse.org/Simulation }
 
parent_class := class<abstract>:

    TriggerDevice : trigger_device

    OnPress(Agent : agent):void=
        TriggerDevice.Trigger(Agent)

child_class := class<concrete>(parent_class):

    @editable  # This can be assigned
    ItemGranter : item_granter_device = item_granter_device{}

    @editable  # This cannot be assigned
    TriggerDevice<override> : trigger_device = trigger_device{}

concrete_inherit_issue_demo := class(creative_device):

    @editable
    ChildClass : child_class = child_class{}

    @editable
    Button : button_device = button_device{}

    OnBegin<override>()<suspends>:void=
        Button.InteractedWithEvent.Subscribe(ChildClass.OnPress)

Expected Result

Ideally, the TriggerDevice editable in this example should be assignable in UEFN, or, if this is the intended behavior, the user should be made aware that devices in abstract classes cannot be overridden.

Observed Result

When assigning editables in UEFN to the creative device in this example, only the ItemGranter device can be assigned, the (overridden) TriggerDevice simply does not show up.

Platform(s)

Windows 11, UEFN 29.20
