I have loaded a library into into a file. With that library, I have created constructions, construction sets, schedule sets, etc. for the model. I have not yet assigned those items to spaces though.

I save the file with these newly created items. When I close the file and open it again, all of that work is gone.

Can anyone offer suggestions on this issue?
