In red shows the incomplete titles. This is Stock report from Analytics. As you can see it has the same product title and missing the attributes as this is a variation product. The link to the product is here: https://beautysouq.com/product/avital-eyelash-black
If I will remove one attributes from this product and the product will be with two attributes (it has 3 now), then the titles show the attributes.
Please find attached screenshot that shows how the variations of the product shown if it has more than 2 attributes. I have tried with different attributes and as soon as more than two attributes are added, the title does not show details of variation.
