LRS Editing tools do not recognize selected centerlines when loaded more than once into a map.

Workaround

1. Open a new map within the .aprx and load a single instance of the registered LRS Centerline layer into the map.
2. Remove all instances of the LRS Centerline layer from the active map.
3. Save the project.
4. Close and reopen ArcGIS Pro, reopen the Location, Referencing Pane.
5. Load a single instance of the registered LRS Centerline layer into the map.
