Adding features to a project causes the basemap to be distorted in ArcGIS Pro

Description

Features can be created in ArcGIS Pro using the Create Features tool on the Edit tab. In some instances, adding the created features to a project causes the basemap to be distorted.

The image below displays the map in ArcGIS Pro before creating the features.

Cause

The coordinate system of the added feature layer in the project is different from the coordinate system of the basemap. This is due to some inevitable distortion that comes with transposing a curved surface to a flat surface. Some projections preserve certain properties of a layer, such as the shape, distance, area, or direction. Esri recommends adopting similar coordinate system definitions among the layers to avoid inaccuracies from misaligned data.

Solution or Workaround

Specify the same coordinate system of the newly added feature layer with the coordinate system of the basemap. Refer to ArcGIS Pro: Specify the coordinate systems of maps and scenes to do this.
