Can you replicate this problem using the -spmap ancillary- datasets?

Both the maps in the example below produce regional borders:

use "Italy-RegionsData.dta", clear
spmap using "Italy-RegionsCoordinates.dta", id(id) name(gr1,replace)
	
spmap using "Italy-RegionsCoordinates.dta", id(id)                 ///
   point(data("Italy-RegionsData.dta") xcoord(xcoord)               ///
   ycoord(ycoord)  fcolor(red) size(*1.5)) ///
   name(gr2,replace)


Another way is to use the -polygon()- option

use "Italy-OutlineData.dta", clear
spmap using "Italy-RegionsCoordinates.dta", id(id)                 ///
	point(data("Italy-RegionsData.dta") xcoord(xcoord)               ///
        ycoord(ycoord)  fcolor(red) size(*1.5)) ///
	polygon(data("Italy-RegionsCoordinates.dta"))
