Buffer features do not appear circular in ArcGIS Pro

Description

When creating a buffer around point features in ArcGIS Pro, the buffer features appear oval instead of circular.

Cause

The map data frame is set to a geographic coordinate system (GCS).

Solution or Workaround

Change the coordinate system of the map data frame to a projected coordinate system (PCS).

1. In the Contents pane, right-click the map data frame layer > Properties.
2. In the Map Properties window, click Coordinate System on the left pane.
3. In the XY Coordinate Systems Available section, expand Projected coordinate system.
   
   
    
4. Select the appropriate projected coordinate system, and click OK. The buffer features in the map appear circular.
