New Custom Rise Blocks not Appearing in Review

I just created and used my first custom Rise blocks--excited about this feature so I don't have to jump into Storyline to create simple interactions. 

 

One issue is that the custom interactions aren't showing in the review link I've created. 

I can seem them in preview mode in the course but not in review. There's no placeholder etc. It just looks as if it doesn't exist. 

 

Is this a known bug?
