Hi Nora and all,

I struggled sometimes with a similar problem but didn't know that the
phantom points was plotted at lat/long (0.0).

I knew that they didn't have valid geometry.

I guessed that it happened when I use a shapefile and deleted some points
during in editing mode (using backspace). I think, it deletes the geometry
only, but not the (line in attribute table).

Can you try this ?

Thanks
