Component disappear in Editor

I've been learning ISWDK for a couple of weeks. I like it: it's really cool. I finished the tutorial and almost everything works, but there's one thing I'm not clear on: when I try to create a "prop" on an Entity or Enum component, Meta Spatial Editor doesn't compile (or at least the component disappears) after pressing the Refresh button. It definitely looks like a bug because the documentation cites examples with Entities and Enums. I copied and ran it, but while it doesn't give any errors on the code side, the component on the editor side disappears. All other types are visible and their parameters are accessible from the UI. I'd like to make a tutorial explaining how to migrate from Unity to IWSDK, but I'm missing this step.

Here Locomotion is available in Meta Spatial Editor:

export const Locomotion = createComponent('Locomotion', {
      test: { type: Types.Int8,  default: 1 }, 
});

Here Locomotion is NOT available anymore in Meta Spatial Editor:

export const MovementMode = { Walk: 'walk', Fly: 'fly' } as const; 
export const Locomotion = createComponent('Locomotion', {
      test: { type: Types.Int8,  default: 1 }, 
      mode: { type: Types.Enum, enum: MovementMode, default: MovementMode.Walk },  // <--
});

Where I wrong?

Sdk: 0.2.2
Meta Spatial Editor: v11.0.0.10

Many thanks in advance
