naval cards

I am trying to help a modder fix some oopses in his mod. The problem for one faction is that one card (bireme) is different from the rest. The ships and their color schemes were left vanilla. Since I have checked everything in the text files I can find and the unit card files and I still have this problem, I need the community's help.
files I have checked:
data/descr_model_strat
data/descr_model_strat/textures
data/ui/units/romans_brutii
data/ui/unit_info/rmoans_brutii
data/export_descr_buildings.txt
data?export_descr_units.txt
