Subject Area - Department Hierarchy(Department Levels) coming up as blank columns

Summary: Subject Area - Department Hierarchy(Department Levels) coming up as blank columns

Content (required): Hi! I'm trying to create a subject area analysis that displays department hierarchy broken down column by column along with department specific details such as headcount, etc. However, despite having set up the hierarchy within Workforce Structures, the Hierarchy folder components, such as Level 1 Department and Level 2 Department, come up as blank fields. If I'm not mistaken, the department levels come from the table: PER_DEPT_TREE_NODE_CF. This table, however, is coming up with no data as well. Is there a specific step that needs to be taken in order for this field to populate?
