Hi @zanematthew,
I followed your instructions in the link you sent, but I’m not seeing the bug. When I removed terms from my import file, then updated my import with it, it removed the term associations from the post (note: it will not delete the terms from your site, it will just remove their relationship to the imported post).
It’s possible that there’s another plugin on your site that’s preventing the terms from being removed. Please try adding this code to your child themes functions.php file and see if it fixes it:
function wpai_wp_all_import_use_wp_set_object_terms( $use_wp_set_object_terms, $tx_name ) {
return true;
}
add_filter( 'wp_all_import_use_wp_set_object_terms', 'wpai_wp_all_import_use_wp_set_object_terms', 10, 2 );
If that doesn’t help, please replicate this issue on a sandbox site at https://www.wpallimport.com/debug/ and open a support request at https://www.wpallimport.com/support/ with the details.
