Set markers by term generates SQL error w Views 2.7

I am running Drupal 6.14 and Views 6.x-2.7. I've created a View using the GMap style that nicely displays multiple nodes of a custom content type. I want to distinguish one location as the current location, with a different marker, so I've created a new taxonomy with a single term, enabled GMap marker selection for the taxonomy, and selected a different marker for that term.

In the View interface, when I set Marker Handling to By Term (under GMap style options), I receive this error message:

user warning: Unknown table 'gmap_taxonomy_node' in field list query: SELECT location.lid AS lid, location.latitude AS location_latitude, location.longitude AS location_longitude, location.latitude AS gmap_lat, location.longitude AS gmap_lon, gmap_taxonomy_node.marker AS gmap_node_marker FROM location location LEFT JOIN location_instance location_instance ON location.lid = location_instance.lid LEFT JOIN node node ON location_instance.vid = node.vid WHERE (node.type in ('ship_location')) AND (node.status <> 0) LIMIT 0, 10 in /Sites/joidesresolution/sites/all/modules/views/includes/view.inc on line 765.

With phpmyadmin I can clearly see that the table gmap_taxonomy_node exists and contains the settings I selected for the taxonomy I set up.

Any thoughts?
