Realtime Export - preview volume way to loud

Is it just on my computer, or is the preview volume when exporting in realtime a lot louder than in the session?
I am very confused, as the session doesn’t clip when auditioned normally, but as soon as I hit export the playback is all distorted. There is no volume slider while exporting anymore in 11.0.10… why is that?

Sorry but on that little information you gave we cant see what went wrong

Sounds a lot like a Control Room-related double-routing.
