My Custom Map Layer is set up correctly, but Measure values are not showing up on my Map. Why?

A possible reason for this is that the Custom Map Layer property key names have to match the corresponding Dimension string fields.

For example,

TopoJSON	LookML Dimension
"dma1":"New York, NY"	New York NY

Where "dma1" is the Property Key that is mapped to the custom map layer definition. The Property Key is configured correctly, but if the respective strings do not match then the map will show blank.

User either needs to add a " , " to the LookML Dimension values, or remove the " , " from the TopoJSON "dma1" values.
