Hello again 
I now understand that ,On Finished" note should always be connected to ,On Finished" inside the Metasound if it is supposed to stop and go away after it has finished playing. I still have some problems with this. When I spawn the sound into the world I check ,Auto Destroy" and I read that this should make the soound go away and stop taking up extra slots when it is finished playing. For some reason this is not working for me. I always need to add delay as long as the sound and then use ,Is Valid" and then ,Stop" to make the Metasound go away from the world… I must be missing some basic understanding of this. Does anyone know what that might be?
Here are pictures:
I use ,on Finished" inside the Metasound:
I have Auto Destroy:
this is how I now stop the sound:
