I am building a basemap using vector tile packages for the MDTs on our city's fire engines. For some time we have used Unique Values and then a Direction field from the street centerline to draw arrows one direction or the other on top of the streets, using a shape marker but no solid stroke on the line (the streets are drawn with a different layer). We imported this symbology from ArcMap. I have noticed that the symbols are not drawing properly in the vector tile package. In the image below the map being rendered is on the left and the rendered map is on the right...

Any ideas here? I'm using Pro 2.9.1.
