Problem with custom soundsets

I have created mod adding 57 extra, polish soundsets for player, but i noticed 3 "selected" sounds (XXXXf, XXXXg XXXXh) doesn't work ingame. What's funny by default we have the same set of sounds as mine (Male1/ON1) with exactly the same sounds and names and it works fine. Can anyone check it (install it at BG1 or SoD since BG2 game doesn't have pl_PL/sound folder)?

EDIT: Just noticed this bug doesn't concern EET, just BG1 and SoD.
