Audio playing multiple times

So, I have an issue, I'm trying to make a trader mob that plays audio when right-clicked, however, the audio would play multiple times or would play all tracks at once, even when I swapped to a sound that only has one track, it still played multiple times. So, I decided to try using a keybind to do it instead, and at first I thought it would work, but then once more, it was the same issue.

so does anyone know a good solution to this? I am one version down from the current mcreator version, but it doesn't seem like this problem was fixed in the patch notes.
