Custom Form Not Migrating All Data To Cart

[designLEEStudio]

Good Evening,

We hired Shopify Experts to re-design our website and in the process, create custom forms(assets) on our site to collect customer information. We've recently been made aware that 1 part of the form is not migrating to the customers cart and ultimately, we're not receiving the data.

Our website - www.designleestudio.com 

Any Physical Cake Topper Product- https://designleestudio.com/collections/wedding-anniversary-cake-toppers/products/wedding-cake-toppe... 

Here is the Form, Blank

Here it is when I put in random info -

Then here is our cart - 

Unfortunately, it appears that on ALL our forms, not for this specific product or custom asset, that we aren't collecting this Additional Information field at all. 

Does anyone know what I might be missing before I hire a Shopify expert?
