I saw someone mention on the Unreal Slackers Discord that when hovering over the output node, a tooltip pops up that mentions if you have a looping sound you want to continue playing, you have to remove the OneShot interface.
I know a couple of my graphs had loops and one-shots together and that I was attempting to use this interface to affect the one-shots only. I have yet to check if this fixes the issue but I thought I would add that to this thread as a possible solution! Perhaps it’s not a bug after all, just user error on my part
