Sorry ... I'm late in answering ...
The Files .GPI included in my Collection are "error free", I corected it before creating ...
The various GPI (for every Country/Zone) are made filtering by coordinate the POI for every single category.
In my Collections are included the GPX source files as well. If you load any of them in MapSource you will see the coverage.

All is made with my software ManagePoi here: [Only registered and activated users can see links. ]

Bye, Bye
