Creating Equal Floor Heights for 3 story house

[akabuilder 0]

After adding a full basement to a 2 story house my ceiling heights were accidently changed. i need 8 ft. ceilings  (including the basement). After adding a foundation (to my 3 stories) the 2nd story jumped to 10 ft.  I'm not able to change it to 8 ft. without disturbing the other floor heights. I did manually try to change the 2nd floor height in the floor dialogue box. My walkout deck corresponding to the 2nd story also is out of whack. How do I edit my floor without 

disturbing the other floors, stairs, deck, etc.?

Are your rooms all set to use the default ceiling height?
