Hatches shouldn't have anything to do with the libraries, but it looks like you have quite a mess of libraries there.
The hatches are showing as I can see them in some of the rooms.
I assume you mean the wall hatches are missing?
Select a wall and open the composite settings dialogue.
Have a look to see what building material it is using.
Then open the building material settings and look to see what fill is being used.
If it doesn't say 'Missing' open the fill settings and see how it is set up.
