Fix a calendar problem in Wordpress/Woocommerce/Woo Bookings on mobile

I am looking for someone who can fix a calendar problem in my Wordpress website krabi-tours.net. For some reason the mobile version isn't loading the booking calendar properly (have a look at one of the tours on mobile or the screenshot provided). When clicking through to the next month, it works fine. When then going back to the current month , it works fine as well. That means the initial loading of the calendar is flawed. Another thing I want done is the floating sidebar. I need it to stop floating when it scrolls down to a certain point. The booking sidebar will start floating when scrolling down. When the Google map is reached I need it to stop floating. Who can help me with this? Please have a look at the website before posting a reply, too many people offer their service without looking at the website in question. I won't respond to those inquiries. Thanks!
