first load is fine but when i go back to january then go back to february, february 4 and 5 is unselected

thanks for the reply,

I have a button to select all available dates (from min to max) and its working, my question is how can i retain the view to not go to the last day selected?
for example my available days are feb - apr and im viewing the month of februrary, when i select all, my calendar view is now on april.
