Hi David, thanks for the quick reply!
I did think it might be a 3rd party plugin, how would I check if any are in demo mode and change that? The only thing is, the plugins I'm using in this example I've been using no problem for a while now. However I did recently buy and install some new ones, but they aren't in use in this example.
Also, I just bounced it in real-time and there were no white noise bursts however when I Listened to the exported version they were there.
