Hello,I am following this example to display a legend with checkboxes to show/hide the layers.When I load the page, the layer icons are visible, but the layer titles do not show up. Note that I am working with featurelayers and not arcgisdynamicservicelayers like in the example. I am attaching my map.js file. Please let me know if you see anything or have any guidance to get the titles to show up. Thanks in advance, I appreciate the help!
