Hello Brenda,

When I upgraded to org 8.3, my org-habits did not display correctly,
because the PROPERTY drawer where the habit style was indicated came
after the LOGBOOK in my org files.
After using org-repair-property-drawers
http://orgmode.org/Changes.html
my habits returned to their previous appearance.
Hope that helps,
Josiah
