Measurements are inaccurate in ArcMap 10.4.1

When using the measurement tool in ArcMap I am getting measurements that are far longer (by about 25%) than known distances on all images in my map.  Measurement is set to Planar and I cannot change it.  Coordinate system is 1984 Web Mercator auxiliary sphere.  Any ideas how to fix this?
