Possible Bug: Dataset Columns get duplicated automatically

Hi,

Sometimes, while in the dataset view mode, When I change the dataset css or other form values and then save those changes, all the columns gets duplicated automatically and as a result the corresponding column value are shown twice in the designer. This occurs occasionally. I am using CMS 1.7.3.

thanks

Please can you try this on 1.7.4 CMS and if it happens, give exact steps to reproduce along with a troubleshoot.txt file showing what happened CMS side.
