Cannot access values and labels in a checkbox field loop

I have created a view that is set to appear on a particular page on my site. The view collects and displays data from a Custom Post Type using fields that I made using MB Custom Fields. I am doing this because I need custom HTML, CSS, and JavaScript for user display.

The View displays on the correct page, and loops though the Custom Post's Custom Fields and displays them EXCEPT for the fields in a checkbox array.

I am using the Insert Field button and it inserts a loop. Do I need to modify this somehow? I am sure it's something about scope or accessing field values and labels that I just don't know how to do in a loop within a loop.

Can anybody tell me how to do this?

Code for View assigned to page

{% set args = {post_type: 'client', posts_per_page: -1} %}

{% set spotlights = mb.get_posts( args )|sort((a, b) => a.post_title <=> b.post_title) %}

{% for post in spotlights %}

    {% if post.client_spotlight == 1 %}

        <div class="client spotlight">
            <p>
