Yea, i was solving same problem, open the file called playerinfo_general.php (in pages folder). Look for this code (starts at line 104 for me).
Code:
<?php
if ($playerdata['country'])
{
echo 'Location: ';
//if ($playerdata['city']) {
// echo htmlspecialchars($playerdata['city'], ENT_COMPAT) . ', ';
//}
echo '<a href="'.$g_options['scripturl'].
Comment out and change this file as shown. There should stay only country in location. Worked for me.
