Did you know that there is a different style of Railing description? This style does NOT have a ‘Baluster Placement’ dialog box. The only Baluster settings in this form of Railing are essentially to select a Baluster family and set a separation (see image).
If you want to use this simpler type of railing definition, you can still download a sample file from Autodesk that includes this older method.

This issue is similar to using legacy mass forms in newer versions of Revit.
