Hello everyone! I´m accessing your sample link, dhtmlx.com/docs/products/dhtmlxS … mple.shtml and happened the same error that we already found into our application.
We attached the picture, look that the day 20 is missing. This happens only with firefox and IE, could you check the reason?

Your development team could check with more browsers options using this great service: browserstack.com
Hope this problem will be solved soon, we will be waiting your answer.
