Sequencer animation is different when playing it in the level

Hey guys,

I’m trying to create an animation in the sequencer. I’m struggling with a hand placement issue.
I’m using a Metahuman and IK controls for the hand.

For some reason when playing the animation the hand is not placed at the same location as in the sequencer.
In the sequencer you can see it’s at the book, clipping with the dress.
When I play the animation in a montage it’s not at that position. What am I missing?

The character is also sitting a little further ahead… but why is the hand further back then?

My question boils down to: How do you make sure an animation from the sequencer looks the same when played in the level?
