As posted previously on thread, to show drop-down fields that may be hidden, go to the View menu and pick Customize. Then on the Toolbars tab, select the 'View' toolbar and click the Reset button. This will reveal all buttons on that toolbar.

The version you are running is somewhat older than current (I think 90A or 90B). Ledger 9.0D supports resetting the toolbar whether you are in the Maintain mode or the Print mode of the Financial Reporter. Not all versions support this (most older versions only allow this in Maintain mode). If you only have security access to Print Financial Statements and are running an older version, you may not be able to see the Customize function from the View menu of the Financial reporter.
