probably wouldn't have been as frustrating if i hadn't gotten 3 of the same customizations for the same character for a republic character

bought 3 of the companion customizations from the rakghoul vendor and i got 3 of the same one for elana dorne a REPUBLIC trooper companion >.> Couldn't i have at least gotten some for imperial companions even if it wasn't for my character. i know it was random and i guess it's my fault for assuming it was at least for the same faction.
