Bathymetric Gradient Setup ArcGIS Pro Tool only outputs hydro_areas

The Bathymetric Gradient Setup Tool works as expected in ArcMap, producing hydro_areas and hydro_flowlines. The ArcGIS Pro version of the tool does not produce hydro_flowlines and instead only outputs hydro_areas. No errors or warnings appear in the Geoprocessing History for the tool, but under "Messages", the following are printed out:
