Construction stages neglecting supports

Hi all

I am using construction stages to take into account the construction of an arch bridge. In each stage, another section of the bridge deck is mounted. I have attached images of each of the construction stages.

For some reason, the bridge does not interact properly with each mounted deck piece, since i see that the supports of the deck is neglected. Each deck piece seems to just follow the deformation of the initial construction stage #1.

Any good solutions on why this is happening?

Thanks!
