Hi,
The issue is that, the categories are not all imported so when it try to associate the imported product to the imported category, because it can't find the category, the product stay "alone".
I think that I will add some kind of safe check after the product-category import in order to retrieve the products without categories. But for the not imported categories, I currently can't tell you what happen wrong during your import ; the best is to see it directly in your website to understand how and why.
