Can't see all the products I imported in my shop

Hello,
I am having a very hard time importing products to my shop (www.pixby.fr)

For exemple, I added "All booklets" today which has a total of 9 products.
After importing them, in my woocommerce dashboard, on product page I see all 9 of them but the customer only sees 6.
So, 3 products are missing (kinda non visible in the shop for the customer) so I thought it would be an importation fail. I tried to delete the 3 of them and reimport them but the problem persists.

And that's only one category. It's like... not even 2% of all the products I would like to add to my shop.

Is there a fix for that ?
