izayo, i made my own localization file (english) for both the 556 and 762 packs which have more info.
idk if your file even worked i cant remember. anyway, they are here... https://www.dropbox.com/scl/fi/r9cw7fs3zi6kdbqk72xvf/IZY-localization-files.zip?rlkey=smxo9cp0zqhm5u21u0f15mdqy&dl=0
also, i seem to have a problem (server setup) with one of the guns. it errors whenever i select it and then turns into a simple block piece. iirc its the car15, but i will double check it and try to get a log for you.
