Blank label shown on Common Map view containing 'Geolocation Geometry' field for polygon

Problem/Motivation

Cannot display field titles as labels on a common map showing multiple polygons. I have added the title as a field alongside the field containing the polygon points (wkt), and selected the title field as the content source and the label source in the view format settings, but the label is always blank. This works fine for markers, just not for shapes added using geometry/wkt. The title is added to a label (leaflet map) using .bindTooltip(shapeSettings.title); in geolocation-leaflet-api.js. I can't work out how/what to change to feed the title when called by shapeSettings.
