yes, that is correct.  the default entry uses =org-beamer-sectioning=
which is where headings are translated to latex section or frame or
block etc entries *and* where the special beamer properties are
processed.   As you have replaced the sectioning section of
=org-export-latex-classes= with your own, you have lost all of that
functionality.

You seem to want to achieve two things:

1. added your macros into the latex preamble, and
2. add the [fragile] option to each frame.

I would suggest you do 1 as you have done but keep org-beamer-sectioning
as the second argument for the org-export-latex-classes entry.  To add
[fragile] to each frame, I would recommend, instead, using some
automated form of input, such as a yasnippet snippet like this one
(untested):

--8<---------------cut here---------------start------------->8---
#name : frame
# --
** ${1:frame title}
   :PROPERTIES:
   :BEAMER_envargs: ${2:[fragile]}
   :END:
   $0
--8<---------------cut here---------------end--------------->8---

so that typing "frame" followed by TAB would define a new headline,
prompting for the title and possible arguments (with defaults).

HTH,
