Potential Bug? Sequencer ignores focus distance/focal length keyframes on playback

Hi there,
Has anyone ever had issues in sequencer where playback ignores keyframes for focal length/manual distance?

Ive keyed focal length to 200mm but when i play back in the editor it looks more like default 35mm.

When i render, its fine but is very irritating for working/editing sequences. Not sure if this is a bug for UE5.2? This isnt for a game, it is just a cinematic with multple shots to be rendered as a MOV

Any help is appreciated
