Custom post

Hi, i’ve bought a theme with custom posts (Movies) and their own categories (Event categories) built in.
Now i need to import from the old website old movies with different categories in my new one.
I succeed in importing movies with their titles, contents and excerpts, but categories are not assigned at all.
I remember i’ve imported everything once for another website with custom posts and categories, so it’s possibile to do it, but maybe i’m doing something wrong.

This is the content of the first row’s cells of my csv:
post_category | post_title | post_excerpt | Testo (i don’t need this column to be imported) | featured_image | fonte (i don’t need this column neither) | post_content

While mapping the csv there’s no “event_category” in custom fields, just post_category in the main custom post ordinary fields.

I don’t know why it’s not working, maybe i need to reorder my columns or to delete useless ones. It worked some months ago..

Can someone help me, please?
