flatpickr first day of week Monday and shorthandcurrentMonth

I have started to use flatpickr on a form and it's working but want to add couple of options to it. I want to add the firstDayOfWeek so that Monday is the first day of the week and then want to shorthandCurrentMonth so it shows Jun instead of June

I know the option code I have is sort of working as dateFormat: "d-m-Y", works if I change the date format and it shows the date format I alter in the dateFormat line but unsure why the firstDayofWeek and shorthandCurrentMonth is not working,...
