Vendor Bill CSV Import Errors – Invalid Account Ref for Subsidiary

I am trying to import CSVs to update the “Brand” and “Department” fields on a Vendor Bill.

I keep receiving the “Invalid account reference key [Account Name Here] for subsidiary 2” error.  [Account Name Here] = ### Account Name. Accounting Preferences are set correctly to reflect this naming.

I’ve assured that the Vendor and Accounts are indeed linked to this subsidiary so I’m thinking the issue is really something else.

I have 2 lines using  Line ID 0 and Line ID 1.  The account names are properly formatted. We use similar imports for other transactions but only running into this issue on vendor bills. The bills are for the open month.  One line is an expense, so I’m uploading these as separate files, linked by Internal ID. Screenshot just shows expense line but the other csv is similar with different account name using line id 0.
