I haven't seen this before. It might have to do with the structure of your data or possibly some issue with the DataRecordPresenter style, if you are providing your own. The quickest way to get help on this is to 'Request Developer Support Online' at http://ko.infragistics.com/gethelp and provide a sample app with steps to reproduce the issue.
