Physics shapes in Tiled layer not working using xParallax?

I have created a layer in Tiled with some physics objects in it (ones I put into the layer not in Tiled, but later in code via …:insert(XY) )
Now I’m using the xParallax to move this layer but the inserted physics shapes stay in place, while the objects and world (layer) is moving.

What am I missing here? How can I make the physics shapes move with the objects in the layer using the xParallax?

Any help welcome!!!

Thx!
