remove white space from map when using proc gmap

I'm using the following code in sas:

goptions reset=all border ;
goptions colors=(yellow steel purple pink red blue cyan orange green gray 
black);

title1 "Congo";
title2 "11 Regions";
footnote j=r "Congo ";


proc gmap map=mapsgfk.dr_congo data=mapsgfk.dr_congo all density=6;
 id id1;  
 choro id1/discrete;run;
quit;

and it generates the following map:enter image description here

How do I remove the white space inside some of the regions?

The map data is segmented at the ID level. The ID1 value is a truncation of ID. The 'white-space' is due to a segment being associated to an id it does not belong to. Try:

proc gmap 
  map=mapsgfk.dr_congo data=mapsgfk.dr_congo all density=6
;

  * simpler statements per DCR comment, removed format;
  id id;
  choro id1 / discrete;
run;
quit;

I believe there may still be some issues regarding lakes being drawn with a color.
