Siren sharp turns my wav files into hex names and will not work

[N1troZeuZ]

I have the files named similarly to your video tutorial but when I put them in fivem the sirens are mute. after opening the awc files in codewalker and open iv they had been changed to a hash name with random assortments of letters and numbers im unsure of the issue because I tried multiple times and one out of the 12 times I tried one file kept its original name and it was the only siren that worked
