Hello,
Sorry to hear you are having issues.
Not all sound packs have the same sounds included so some sounds maybe missing
that other have .
You can open the app for that sound pack and scroll through its sounds to see what
is there , and you could then edit the sound pack also to add new sounds or delete
a sound or replace a sound with another sound effect you might like better .
See if that works for you .
