Trouble with how Contact Form Email Displays Info from Checkboxes

I’ve created some checkboxes on the contact form of my Shopify site. When I check them and submit, the email that it sends me lists what I set it to say in en.default.json, but it’s followed by a colon (:). When viewed, it looks incomplete or broken. I’d like at least to be able to remove the colon, but I’m having trouble.

in my page.contact.liquid file I have the following code

 
        	
Choose all that apply

        	 Retail

        	  Wholesale

        	  Online

        	  Foodservice

        	 Other
 

This is in the en.default.json file

"contact": {
    "form": {
      "name": "Name",
      "email": "Email",
      "phone": "Phone Number",
      "company": "Company",
      "company_website": "Company Website",
      "company_years": "Company has been in business",
      "distribution-retail": "Retail Distribution",
      "distribution-wholesale": "Wholesale Distribution",
      "distribution-online": "Online Distribution",
      "distribution-foodservice": "Foodservice Distribution",
      "distribution-other": "Other Distribution",
      "message": "Message",
      "submit": "Send",
      "post_success": "Thanks for contacting us. We'll get back to you as soon as possible.",
      "error_heading": "Please adjust the following:"
    }
  },

The email I get looks like this:

Removing the colons is the minimum of what I’d want to do. I’m not sure where that part is formatted.
