Sorry, I can't seem to replicate. Please close ticket. I had to remove them from the page to keep the site live. Now I tried to build a test sample and it is working fine. I had added a current date default and had two instances of the datepicker on the page, but once again, when I built a test it worked just fine. I was concerned about all the other pages on other sites where I've already used, but have not heard of any other issues.
Thanks as always for your fine products and customer care.
