Author not imported first time

Hello

i am importing post in bulk, i have a field “author” in the csv file for import.

in the plugin i have under “taxonomies, categories, tags”

the field Authors (plugin used is publishpress authors)

i pair the field and import the post, but all posts have the fallback user (editor) as author.

if i run the import again, only this time for existing post, and do an update,

the authors are updated as they should be.

i am using the free version.

what m’i missing here?
