Seeing as how you are already adding to the deaths and kills here:

pawn Код:

Deaths[playerid]++;
   Kills[killerid]++;
   KillStreak[killerid]++;

Why are you adding again in the formatted string?

pawn Код:

format(kupdate,sizeof(kupdate),"Kills : %d",Kills[killerid]++);

Try

pawn Код:

format(kupdate,sizeof(kupdate),"Kills : %d",Kills[killerid]);
format(dupdate,sizeof(dupdate),"Deaths : %d",Deaths[playerid]);
