Can't modify my Primary Header in a section - Dawn Theme

I created a custom section called “Video with Text” following by following this thread: https://community.shopify.com/post/1499504

Everything works well. However, I am unable to edit the main header with bold and the sizes options don’t work.

There seems to be a missing line in my video-with-text.liquid code, but I can’t seem to find it what’s wrong. I just tried matching the code with the image-with-text.liquid and still can’t figure it out. Please help!

{{ 'component-video-with-text.css' | asset_url | stylesheet_tag }}

  

    

      

        
      

    

    
      

        {%- for block in section.blocks -%}
          {% case block.type %}
            {%- when 'heading' -%}
              ## 
                {{ block.settings.heading | escape }}
              
            {%- when 'text' -%}
              {{ block.settings.text }}

            {%- when 'button' -%}
              {%- if block.settings.button_label != blank -%}

This is the code in my video-with-text.liquid

Hi @jasondane ,

I fix the code here.

{{ 'component-video-with-text.css' | asset_url | stylesheet_tag }}

  

    

      

        
      

    

    
      

        {%- for block in section.blocks -%}
          {% case block.type %}
            {%- when 'heading' -%}
              ## 
                {{ block.settings.heading }}
              
            {%- when 'text' -%}
              {{ block.settings.text }}

            {%- when 'button' -%}
              {%- if block.settings.button_label != blank -%}
                
                  {{ block.settings.button_label | escape }}
                
              {%- endif -%}
          {%- endcase -%}
        {%- endfor -%}
