Multiple instances of sound group variations

Hello

I've been using MasterAudio for my current project and have hit a small issue.
I am calling variations in soundgroups directly to avoid overly cluttering everything with soundgroups. But these variations only play in one location. I have set Retrigger Percentage to 100 and increased the weight to 10 with no effect.
Here's a call I'm using to start the sound:

idleSound = MasterAudio.PlaySound3DAtVector3("sfx_barrier", transform.position, 1.0f, null, 0.0f, "idle");
And here are the settings I use on the soundgroup and the variation, also console output to show that two calls are being done:



Is there something I'm missing or doing wrong?

Thanks for any help
