how to remove duplicate jerseys in teamgear?

how to remove duplicate jerseys in teamgear? although i remove it in teamgear.dbf, when i load the save game and continue playing. during the jerseys selection screen, it still show up the duplicate. can any1 show me how to fix this? or remove the duplicate?

Probably the easiest, most error-free method would be to restore a teamgear.dbf file that doesn't include the duplicate entries.

Or you could copy the teamgear.dbf in your save folder and paste it in the database folders overwriting the teamgear.dbf of the current database folder & working database folder. No need to overwrite the one in the original database folder.
