Problem media gallery import Magento 2.3

[B10-Max]

I am trying this module, I import from csv, unfortunately the media gallery is not imported ..
In the csv layout as specified by Magento 2.3, I insert:
base_image, base_image_label, small_image, small_image_label, thumbnail_image, thumbnail_image_label, additional_image, additional_image_label..I see all the images but the one in the media gallery is missing

both in the product detail admin panel and in the public area product detail page.
Thanks in advanced

I had the same problem and solved it by fix the storeId in

importexportfree/Model/Import/Product.php

Line 528 in 3cec6d7

$mediaGallery[$rowSku][] = [

Instead
$mediaGallery[$rowSku][]

use

$mediaGallery[0][$rowSku][]
