When running a function from the arcgis.features module using the ArcGIS API for Python with context parameter including {"overwrite": True}, the overwritten feature layer adds an identical, duplicate sublayer to the selected item instead of overwriting.

Use ArcGIS Online Assistant to remove sublayers from feature layer. Note: ArcGIS Online Assistant is not supported by Esri Technical Support.

1. Navigate to assistant.esri-ps.com and log in.
2. On the My Content tab, find the target feature layer and click it. Click View Item JSON.
3. Click the Data tab and click Edit JSON.
4. Delete the duplicate JSON data. Make sure to keep the original ("id": 0). Deleting it all will break the layer and any dependent apps.
