Hi @Adam_Thiel and thank you so much for sharing your thoughts with us! Forms are literally just out, and your feedback are very important si we can make the best adjustments in future updates.
From what I can gather in the screenshot your shared, the info circled in blue do not exist in your Project custom fields, they’re new fields you’ve created directly via the Form correct? If you create a custom field in your project for “Name”, “Email address” and “preferred due date”, you should be able to select them in your forum (instead of creating new fields) and these info should show up in your custom fields!
Also, as it stands we don’t have a “date” custom field, but this is a popular request in the Forum, so hopefully this will be impelmented in teh near future 
If you haven’t yet, I’d recommend adding your vote to this thread: Better Custom Field Type Options
Hope this helps! Have a great Wednesday
