Bug: subtree LaTeX export problems after upgrade [8.1 (8.1-elpa @ /home/brian/.emacs.d/elpa/org-20130906/)]

I just upgraded to org-mode 8.1 using 'package-install' and I think I am
encountering some bugs when
exporting to LaTeX. I am using the following tags
in the header of my orgmode files:

#+AUTHOR:    [my name]
#+DATE:      %B %e, %Y

If I am exporting an entire buffer, "%B %e, %Y" now shows up verbatim
instead of as a date like it used to.

If I am exporting a subtree, I am also forced to re-specify the author and
date with :EXPORT_DATE: and :EXPORT_AUTHOR: or else the name is changed to
"Charles Cave" and the date something like 01-01-2009.
