Standalone Mode Spawns only Base Mesh in a Blueprint


I’m having an odd problem where I’m using a level blueprint to spawn a static mesh blueprint. In Play in Editor, it works fine, but in Standalone mode only the base mesh is spawned and none of it’s components.

Here’s my level blueprint:

The base static mesh in this blueprint is just a cube (that isn’t visible and has no collision) that has a CineCamera component and another static mesh component that is a randomly selected static mesh of a car. Two other components of the blueprint are an ActorSequence and GameplayTasks for timing.
Here’s a snapshot of the Static Mesh Actor construction script and variables:

Any ideas why I’m only getting the cube and nothing else in standalone mode?
