Why are my product variants missing in Oblero?

Hi everyone!

So I added my products to Shopify from Ali express to Shopify through Oblero but, I just noticed that in the notification section, it shows a list of missing variants written as:

“Shopify product -variant name- variant is missing”.

But the thing is when I go check in the product list in my store everything looks fine, so I am not sure what I suppose to investigate. Did anyone have the same problem?

Would be cool if someone could help me out, thanks!

I also received notifications from Oblero that they are no longer importing products with missing variants. My store looks fine but am wondering if I will have issues when I have a sale. I have deleted a lot of variants using the correct methods. Do I now have to delete my product and then install it with no variants? Or delete variants in Oblero before pushing to my store? I would enter the variants back in but it is confusing as to exactly how to do that and there are a lot that I have deleted.
