Match Cinematic Viewport when in PIE mode

Very confused.
I have several cameras set up with proper framing, focal length etc in Cinematic Viewport.
I then pilot one of the cameras and hit Play(PIE mode)
The same camera is selected however my view changes dramatically to a wider FOV.

Why is this happening?
How do I match my current framing in the Cinematic Viewport when I enter PIE mode?
