I have a google Layer map on top of which I have added a raster layer of Image and then mapped image coordinates from Google layer.

I made transparent (75%) image map layer and now mapping and creating polygons on top of image layer (Added new shapefile layer) I drew few polygons and then saved it.

When I reopened the file, clicked on toggle editing, I could see my polygons, but I am not able to add/edit/delete existing/new polygons in that shapefile layer. (All icons are disabled)

Is this expected behavior?

My old question on what exactly am I doing. How to create/obtain district data for Singapore?
