yes - it only seems to show one page worth of your countrymen, and assuming you are from a country with more than one page worth of players then it seems to show random players fom your country.
dont know of any way to make sure you get all except to shorten the rating range to a degree where there are less than a full page worth.
i often thought it would be a good idea to be able to view all from ones country and sort by score, name etc...
alas, no action on that yet.
you could always use the "my buddies" section as i do.
