So I just decided to give up on this plugin. For those who had the same issue as I did. There is a premium plugin in Code Canyon called Contact Form 7 – HubSpot Integration https://codecanyon.net/item/contact-form-7-hubspot-integration/
It works flawlessly and is actually much easier to map the CF7 form fields to your Hubspot form fields. I normally wouldn’t promote another plugin in a product’s support forum, but it appears this author has abandoned the plugin, so just trying to help others out who have had the same issues as me.
