a small bug with repeatHeaderCount config setting.
$intCurrentUserCount and $intPageUserCount are incremented right now for every user and only then, after that, there is the check if the user is hidden


Therefor the setting for repeatHeaderCount is interpreted wrong.
So I changed in file /include/showmonth.function.php (line ~607)
toforeach ($users as $usr)
{
$intCurrentUserCount++;
$intPageUserCount++;
$monthBody='';
$U->findByName($usr['user']);
//print($usr['group']."|".$usr['user'].'<br>');
if ( !($U->status&$CONF['USHIDDEN']) )
{
if ( checkAuth("viewCalendar",$U->username) )
{
and everything works like it should!foreach ($users as $usr)
{
//$intCurrentUserCount++;
//$intPageUserCount++;
$monthBody='';
$U->findByName($usr['user']);
//print($usr['group']."|".$usr['user'].'<br>');
if ( !($U->status&$CONF['USHIDDEN']) )
{
$intCurrentUserCount++;
$intPageUserCount++;
if ( checkAuth("viewCalendar",$U->username) )
{
