Spawn Dialogue will not auto destroy

Hi, I am currently trying to use the built in Dialogue sound system, but every time the sound finishes it repeats itself. Its been driving me crazy trying to get this thing to actually work. So far all I can do it manually destroy the dialogue, with a button click. This simply wont work because I need it to finish talking, and destroy itself. Is there something i’m missing?

I found the issue, the voice performer recorded multiple takes on the same file without telling me.
