two labels for one polygon

[Erwin v.d. Bij]

I have a problem with showing labels of polygons in Oracle Spatial/mapserver environment. I have polygons and their labels defined in the same layer group. The following happens: if I add a polygon to the database the polygon will be shown with 2 times the same label. If I add a new polygon, the old polygon will be shown now with one label and the new polygon with two labels again. Any idea?
