animation sequence : override instance data broken?

Hello,

Im trying to play a animation sequence from the level blueprint. That itself works well, however there seems to be a problem with the new (4.19) feature “override instance data”. I read here that i can use this feature to “offset” my whole animation sequence. My sequence without override looks like this:

And my animation after i offset it by Location (0|-200|0) looks like this:

The 2 hands are aactors by themselves. But i exspected that all of them gets offset by the same amount but somehow they are seperated by miles. I cant find a solution for this, did anyone experience something simular?
