Skkiped dates not working!

It is the plugin with the best capabilities that I have seen so far but it does not work “skipped dates”. I have Saturdays and Sundays disabled in the plugin settings but it still uses them to estimate a date. I have checked the time zone in the wordpress settings as well as added <date.timezone = “Europe/Madrid”> in the php.ini file and it still does not work. Can you help me? Thank you
