How to Manage Redwood search with multiple columns with same name in Item classes

Can anyone help in controlling the display in the redwood search for the some of the EFF attributes whose names are same and they are specified at each class.

Now, the problem is in the Redwood search, In order to display columns we need to add them all, but as there are many columns with same name, they are coming multiple times in the search.
