That heading can be hidden with CSS. Add the following to the theme’s custom CSS area:

.cn-entry-content-block-meta > h3 {
    display: none;
}

Since you bulk imported blank values, there really no way to hide the key value name without perhaps some fancy javascript.

There is a path forwards though…

You could follow this tutorial on adding custom text fields. You would register the custom text fields using the same ID that you used in the other tutorial. Do thing will remove them from the “Custom Fields” metabox but display them as their own input. There will also no longer output in the “Custom Fields” content block on the template. Instead … the tutorial also covers how to display them in the template. Following those instructions will ensure the field is not displayed if it has no value.

Hope that makes sense! Let me know.
