Meta Box

I just started over and tried two different ways of creating a form and neither are working. First, I created a form with shortcodes, and second, I used the MB Front End Submission element in Bricks.

Shortcode version:
I tried to create the illusion of a multistep form and adding shortcode from my custom fields into tabs in Bricks. For example:

Tab 1: [mb_frontend_form id='listing-type,location,business-hours-display' post_fields='title,content']
Tab 2: [mb_frontend_form id='listing-packages']

I hid the submit button with code except for the last step. I realized hiding the button on each page might end up with only the data from the last tab with the submit button showing up, but,in fact, the entire post was empty.

When I test this out, it gives me a notice that the form is successfully submitted, but there is no record of it on the back end.

Additional questions:
I've seen this asked before but it hasn't fully answered what I'm looking for. How exactly can post drafts be saved via front end submission? I only see submit buttons.

I'm trying to break up the form since it requires the selection of packages to purchase listings. If they select a paid listing, a pop up form will appear for payment. I'd like users to be able to save a draft of their post if they pay and don't want to complete the rest of it right away.

Thanks.

Yeah I'm realizing my conditional logic isn't working anywhere now. Here's what I've tried to fix:
Disabled all plugins
Changed themes
Cleared all caches
Flushed permalinks
Ensured conditional logic extension is enabled

Nothing is working.
