Windows Explorer doesn't recognize the Long/Lat ref

Windows Explorer can read the longitude & latitude coordinates written by this, but it doesn't pick up on the N/S or E/W in my tests so far.

I'm ultimately consuming this in a VB.NET Framework program using my own C# DLL on .NET Standard 2.0 as a go-between.

I just pass a simple string char to my DLL and it does the conversion and saves, like so:

                var file = ImageFile.FromFile(source);

                GPSLatitudeRef gpslatref = new GPSLatitudeRef();
                if (latref == "N")
                {
                    gpslatref = GPSLatitudeRef.North;
                }
                if (latref == "S")
                {
                    gpslatref = GPSLatitudeRef.South;
                }

                GPSLongitudeRef gpslongref = new GPSLongitudeRef();
                if (longref == "E")
                {
                    gpslongref = GPSLongitudeRef.East;
                }
                if (longref == "W")
                {
                    gpslongref = GPSLongitudeRef.West;
                }

                // write new values

                file.Properties.Set(ExifTag.GPSLatitude, latdeg, latmin, latsec);
                file.Properties.Set(ExifTag.GPSLongitude, longdeg, longmin, longsec);
                file.Properties.Set(ExifTag.GPSLatitudeRef, gpslatref);
                file.Properties.Set(ExifTag.GPSLongitudeRef, gpslongref);
                if (String.IsNullOrEmpty(dest))
                {
                    dest = source;
                }
                file.Save(dest);

Is there any trick that will get Windows Explorer to see the lat/long refs?
