Hello,
I am having the same issue even though i set the category in the import. Seems like the importer is not setting the category at first, the post is then being classified as uncategorized (or default category), and only later being assigned to the category i set in the import.
I am in fact importing on two different wordpress websites and this assignment to the default category is only happening on one of them but have not been able to figure out what the issue is.
