Multiple images upload for product variations

G’day,

I’m using All Import plugin but I got stuck with one issue.
I have multiple images for every product variation. I need to upload them and attache to my product.

As I can see when I prepare a template for my CSV, the system (all import plugin) see all the images and it does attach all of them to correct variation as well as to the main gallery.

The only problem is that I see only one image of a variation instead of three. From backend I can also see that all images attached to the gallery, but in my variation I can see that there is only one image uploaded (instead of three).

You can see this screenshot from my backend: http://joxi.ru/RmzG41BIYE6qX2

Practically the question is: how to add variation image gallery pictures through csv to make them to be seen from frontend.

How to solve this problem?

Thank you in advance.
