"is Greater than or equal to" option is missing in the filter criteria in Sarepoint Designer

Most of the users face some problems with not having the right operators in the Filter Criteria dialog of a DataForm Web Part speciall when they are trying to filter by was a date.

Once of my end user have same problem and using option 2, his problem was resolved.
