Calender jumps to the current date while selecting multiple

I have a big problem with the multiple date picker. Wheneaver I enter a date (for instance in August) the date picker automatically jumps back to the current date. So I have to go to August again manually which is very annoying if you have to add dozens of dates.

jQuery("#txtDate").multiDatesPicker({

dateFormat: 'dd/mm/yy',

showOn: 'focus',

minDate: +1,

multidate: true,

maxDate: ScriptVariables.Get('ExpiryDate'),

maxPicks: ScriptVariables.Get('MaxDatePicks'),

showOn: "button",

buttonImage: "http://img.icbdr.com/images/images/jpimages/mdp-icon.png",

buttonImageOnly: true,

buttonText: "You can use this feature to schedule the refreshes for this job."

});

var SelectedDates = ScriptVariables.Get('SelectedDates');

if(jQuery('#rMultiOpt').is(':checked'))

{

jQuery("#txtDate").multiDatesPicker('addDates', GetSelectedDates(SelectedDates)

);

jQuery("#txtDate").val(SelectedDates);

}

function GetSelectedDates(dates)

{

var myDates = [];

jQuery.each(dates.split(','), function(){

myDates.push(jQuery.trim(this));

});

return myDates

}
