You have quite a few errors in your tree (shown by "!"). Some have come from underconstrained sketches and this is causing features to fail etc. You also have a lot of Inserted Parts and I can't tell if they have errors as you have only sent the one Part file. In any case the errors in your tree are causing features and by extension the bodies not to be shown as effectively they can't be created.
