Splunk 4.3 -> Bug -> Actions: Export Results

In Splunk once the search completed the user has the option to export the result set by selecting the following menu "Actions: Export Results". In splunk version 4.3 seems to be broken. The user is able to export the result set in CVS format but the content of the csv file is not consistent. It works without any problem in 4.2.1.

Is there any work around? or Is it a known bug?

Thanks
