Hello,
I saw the screenshot you attached. By default the main product image is displayed to the product grids on the shop page and other pages. The Images added to the product are WooCommerce functionality and our theme doesn’t influence this.
You cannot make the first image in the product gallery to be the first image. It requires customization and this is beyond our limitations and support policy.
Images are controlled by WooCommerce itself and WooCommerce provides some options to set the thumbnails cropping that you can set from Appearance >> Customize >> WooCommerce >> Product Images.

Best Regards.
