I have created a custom vector basemap from the ESRI Light Gray Canvas. The original Light Gray Canvas shows the road labels on top of my vector layers in my webmap. However, the Light Gray Canvas I customized shows these labels under my vector layers in my webmap. The only line of JSON code I changed in the root.json was the font size for major roads. In the attached screenshot I circled an example of the road label under my vector layers. Given that I did not change any other line of code, seems that once I modified the Light Gray Canvas it seemed to place all the road labels under my vector layers. Any ideas on a solution? Is there a line of code I need to modify in the root.json?
