I have an issue with Shapefiles opened in QGIS.
I developped an application with a class able to read data from an Oracle database, and convert them in Shapefile.
This class follows the ESRI specifications from here : https://www.esri.com/library/whitepapers/pdfs/shapefile.pdf

You can find in attach 2 samples :
- 4480___S12_060_4 : there is only one polygon, but it is not displayed on the map
- 4480___327550 : there are 8 polygons in this one, and all of them are well displayed

The strange thing is that the polygon from "4480___S12_060_4" is common with "4480___327550", but in one case it is not shown, and in the other case it is shown (see screenshot in attach)...
I have no problem when I open these files with MapInfo.
I don't have ArcMap to check on this side.

Are you able to check if it is a bug from the Shapefile or from QGIS ?
I spent some hours to check what's wrong, but I have no more ideas right now...

Many thanks.
