Search Table Showing Extra "IBA" Value Append to Table Columns Headings

Hi, we use Windchill 9.1 M070.

Last Week we created new Saved Search.

Its gives results as per our requirements , but one minior Thing is it display additional "IBA" String Append to Coulmn name of Table.

As show in below Fig, i.e Before search, Table Having Column Names "DRAWING_NUMBER"

but after Result as shown in Bottom Side there is Extra "IBA" added before to column Name

previous Column Name change from "DRAWING_NUMBER" to "IBA|DRAWING_NUMBER"

Why this is happenings..

I aslo attached Method server log file with this..

Thanks,

Vivek
