Cinematic Transmissions - Wait

I'm having trouble getting the delay in Cinematic Transmissions to work. In single player, long wait times in the Modify Duration: Add X seconds and wait doesn't seem to work (tried huge wait times but it doesn't add any delay at all)

Putting a polled wait after the Cinematic delays it long enough, but the text disappears X seconds in. Is there a way to fix this? (Single and multiplayer, if there's a difference :/)
