Problem with plugin Content Excel Importer Pro

Hello

I purchased the plugin Content Excel Importer Pro to be able to massively import data from a custom post type called Directory on my website.

I designed the page using Bricks. The CPT is built with Advanced Custom Fields.

I have two issues related to the featured image:

1. In Advanced Custom Fields there is no featured image field so in my theme’s functions.php file, I created one to make the image of the logo field the featured image of my post (in the 4 test posts that I created before doing a first test import of the excel, it works)… But even though I drag the “logo” label from the imported excel to the right place, the featured image does not appear on anything imported.

2. The second problem is that, despite the fact that in the excel file with the urls of the images they all come with their SSL, when importing them, they all appear with http (not https) and therefore the web appears as insecure because it contains images with url’s http (for example: https://maraluisas.sg-host.com/wp-content/uploads/2012/12/sf_art1.jpg)

How can that be fixed?

Thank you so much
