PROBLEM
In the default version, the flow direction arrows show up. However, when viewing the secondary version, the flow direction shows indeterminate.
The flow direction shows indeterminate because the primary and secondary versions are not reconciled.
Reconcile and post changes from the secondary version to default and the flow direction is shown. Reconciling versions and posting changes requires an ArcGIS Desktop Standard or Advanced license. For more information on reconciling versions and posting changes in ArcMap, refer to: ArcMap: Reconciling a version and ArcMap: Posting changes.
