When Insert date command through "Date & Time" button is executed for the first time, the date is added to the document as expected. However, if the date is inserted once again, then the date is inserted twice. If date is inserted for the third time in the document, then it will be inserted three times and so on.
Hi, The issue is fixed in out latest LIB release with version: 2015.2.831. Best Regards, Aylin, The Telerik Team
