[Plugin: Contact Form 7 Datepicker] Year and month buttons not showing

HI,
The calendar pops up, but the buttons to change the month and year on the top don’t show, but the functionality seems to be there. If I scroll over the places the buttons should be, the “Move a month backward,” text etc. shows up and if I click on the place the buttons should be, the calendar changes, but the actual buttons are missing.

Please help….

thanks,
