Import of variable goods?

Question

WordPress

Essence.
It is necessary to unload the catalog from the site natali37.ru I do it
through q-parser.
Downloaded the demo.
I ship to Wu Commerce.
Everything is ok, but: variable products do not work. That is, for a T-shirt, for example, you cannot choose a size or color. And this works on Natalie's website.
Questions: does the parser unload crookedly? Or does he not know how to unload variable goods at all?
How can I still download the catalog and upload it correctly?
A bunch of sites with the same product and it works for everyone
