Loss of faq categories in the faq post edit area

Hi,

Since updating to WP5 with Gutenburg, there is no longer any way to add faq categories in the faq post edit area. They used to appear on the right hand column, but nothing there now.

I see I can assign them on the main faq page ( /wp-admin/edit.php?post_type=gs_faq ) by using the quick edit feature.

But is there a way to get the categories back to the single post edit area?

Thanks
