I am trying to build a Nintex workflow against a library with a custom document set content type in Office 365 (SharePoint Online). However when I try to edit task form for a task within the workflow, I could not see few of the list item fields in the task form designer. It is not field type issue as some of the columns available are of the same type like choice field, text field etc. And I could not see any people fields and currency fields. Any help regarding this will be really appreciated.
