Hallo Abdo,
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). This makes sense, thanks. I will test it.

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 ?

I have created a NEW shapefile for each of my areas. Attached find one of these layers. It was created (geometry type: points) and saved. I then "edited" the layer and adding points using "add pint feature" When realising that there were "phantom" points, I selected the visible points and saved it as a new layer. I do not use GeoPackage as as layers but will definitely try it in future. Thanks again - have a great day.

Did you create the shapefile specifically and newly in QGIS, or did you reuse some old shapefile where you just deleted features? Shape is a brittle format and can easily get corrupted, especially if different apps and programs got their hands on the same file. QGIS always had bugs with shapefiles, e.g. this one: > https://github.com/qgis/QGIS/issues/19349 I don't work with shapefiles at all anymore, I just treat them as data- interchange format. If you receive a shapefile, import it into geopackage, spatialite or postgis, when your done editing, export it again as a new shapefile. Saved me a lot of headaches. Export your points in a temporary scratch layer that you then save as a new shapefile under a new name, so QGIS won't use the old sidecars anymore. Try editing the "new" shapefile and see if the error persists. Try to create a completely new shapefile with the same columns and see if the error persists, try to save your shapefile into a different format and continue editing the new format. I highly suspect the shapefile is broken and thus creates phantom/mystery geometries. Do you have any other layers joined or connected to the offending layer? It could be that the creation of a point triggers further action. What are your settings in Layer > Layer Properties. , tabs "Actions" and "Attributes Form"? Do you have an expression saved somewhere as an automatic input field? I had similar problems with mystery points added in QField, no more problems since only using geopackage. I also tried to recreate your problem, but my newly created shapefile layer only shows the points I added. Can you share your shape with us, or does it have confidential data?
