This may well be deliberate, I don't know and just want it clarified so I know for future reference and I couldn't find it asked elsewhere.

I am the DM with all the books and I am sharing them with my players. They have access to the monsters, feats, character stuff, etc, etc.

However, anyone looking at my shared content does not get to see anything that comes below any red line in the description of monsters. Weirdly this includes basic rules creatures such as dragons or doppelgangers where they can see either a short description or the details such as the rules for lairs for dragons but not all the bonus stuff that describes the character behind for example a silver dragon. 

Is this something I have done incorrectly or is it  just a feature that only those subscribing or owning the books gets to get that? Or is it a bug? 

Thanks for your help!
