Need help with distant sounds!

Hello, i've been making a sound mod for the latest version of Project Reality, i made the gun sounds work properly, etc, the issue is related to the Distant Firing sounds, i replaced the original sounds (in this case the fal_far.ogg file) with the same format and bitrate, however the sound simply dissapears, i checked and realized distant sounds don't actually need loop regions

what am i doing wrong? same format and bitrate, but the sound simply dissapears

any idea? :m1helmet:
