Hi, in your case the vector map (given as 'to' in v.distance) contains some areas (bunch of boundaries and centroid inside). Category number of area is assigned to the centroid. Geometry feature (point, line, boundary, centroid, face or kernel) can have more categories in general. The message from v.distance warns you that there are more categories assigned to the area (i.e. centroid) in given layer (to_layer). The last found category in given layer is taken for computation, maybe v.distance should be fixed to handle also multiple categories in one layer(?)
