Concatenator Breaks w/Multiple Nodes Attached (sound cue)

If I plug multiple wav nodes into the first input on the Concatenator it stops working.

The first image here the concatenator is working as intended.

But if I connect the second upper node it stops working.

I’ve also made an [Example Video][3] to show the issue. (What I’m doing in this video isn’t my goal, it’s just the best way to show an example of the issue)
