OSM - Mapnik - areas rendered as background color
<p>I am generating maps using Mapnik and OSM data (postgres and shapefiles).  My problem is that quite a few areas, most of which I believe are considered "landcover", are rendering as the background color.  The areas render as background color regardless of zoom level.  </p>

<p>For example, in between streets, everything is blue.  There are some forests that render as expected, but most of the residential areas are just blue. </p>

<p>I am using Mapnik 3 with a stylesheet.  This is running on Ubuntu 16.04.  </p>

<p>The images below show what I am generating, and what I would like to see (based on what is on Openstreetmaps).</p>

<p>Any suggestions as to where I should look to solve this problem would be greatly appreciated.</p>

<p>Thanks.</p>
