Compilation error with Evaluate Chooser node when getting All Results from Subclass Of table

Trying to use the Evaluate Chooser node in the All Results mode with a chooser table that returns the Subclass Of type results in a compilation error ("Array of Actor Object References is not compatible with Object Reference"). It compiles error free when using the First Result mode.

• Create a new Third Person template project.
• Activate the Chooser plugin and restart the engine
• Create two Blueprint classes derived from Actor, name them BP_ActorA and BP_ActorB
• Create a Chooser Table of type Generic Chooser, set the Result Type to SubClass Of and Result Class to Actor. Name it CT_ActorSubClass.
• Open CT_ActorSubClass and add two Rows of Class. Select BP_ActorA and BP_ActorB from the dropdown for each row. Save and close the Chooser Table.
• Create another Blueprint class derived from Actor and name it BP_EvaluateChooser. In its EventGraph, add an Evaluate Chooser node and connect its execution pin to the Event tick
• Click the Evaluate Chooser node and in the Details panel, select CT_ActorSubClass for the Chooser field and All Results for Mode
• Add a variable (by clikcing the + sign in the left panel), derive it from Actor in the Object Types and change it to a Class Reference. Name the variable "Random Actor"
• From the Evaluate Chooser's Result output pin, pull off a "Random Array Item" function node
• pull in a Set Random Actor node, connect its input with the output from the RANDOM node and connect the execution pin to the Evaluate Chooser node.
• Press Compile. There should be an error saying "Array of Actor Object References is not compatible with Object Reference"
