Transactions: Category Dropdown Values Missing

I recently added the Transaction tab to a new budget. When the autofill runs, the Category dropdown of values does not get added. It stays as a cell and not the value of multiple options. Any troubleshooting tips?

How did you add the Transactions tab to a new budget?

If the goal was to create another linked Tiller spreadsheet, use the Create a Spreadsheet link from the Tiller Console.
