Extra shopify radio button appears on my custom contact template

I am using my contact template to create new contact forms.

I have created several forms successfully however when I create one with radio buttons, for some reason, I get an extra button appearing at the start of the displayed form. It doesn’t do any functional harm, it’s just annoying and possibly may confuse a customer.

{% if page.title == "FormXYZ" %}

                

                This online form...
                

                  

What pack size do you require?

                      4 Pack 
                      8 Pack
                  

                  
  
                 
                      
                  
                  
                    
                      
We usually respond within 24 hours.
              

              
              {% endif %}
