Handlebars unable to render certain properties of an object

I'm having a really spooky problem with handlebars - and I'm wondering if anyone has run into this before.

I have an object that I'm trying to use handlebars to render - and despite all of the properties pulling across in - some properties won't render/show.

How the object looks in the database

The Handlebars rendering code

  <h1>Complete object</h1>
  
  <br>
  <br>
   
   
   
   
  
   
   
   
   

---

How it renders on the page

How it looks in inspector

I've been pulling my hair out at this - and I'm really not sure what I'm doing wrong.

Thanks for any help/insights anyone might have
