I created a choropleth map for Portland showing distances from the city center. Now the problem is after I set any symbology to the map, it dissapears when zooming in after a certain extent. Show map at all scales option is checked in the layer properties. So I don't understand what else can effect this dissapearance. It is a problem for me because the same thing then happens in layout view and I cannot print out my maps with zoomed in view. Please if someone can think of a solution it would be great.
