Hello Dave, am I wrong or is your map connected to two distinct tables with the same key (cat) ? then the behavior you describe may be related to a confusion on the type of features holding 'cat' values. For exemple in the case of a polygon map, you need to define which type of object handles cats (i.e. boundaries or centroids). Just to check, you can have a look at this wiki entry : https://grasswiki.osgeo.org/wiki/Vector_Database_Management#GRASS_GIS_vector_management_model
