Class and Department Features missing in Quickbooks Power BI app

Two important features in Quickbooks Online are not flowing through to the Quickbooks Power BI App.  Those two features are the Class field and the Department field.  The field "Class" appears to show up in the Field Table - unfortunately when it is clicked, nothing appears.

The "Department" field is entirely missing from the Field Table.  Adding these to fields would make this app more more meaningful since I use these two components often.

Thank you,

Jimmy
