Reply to myself:

I edebugged the ox-latex and studied what's happening.
Who wrote this code? you shouldn't do things like this...
The code is overwriting the defcustom'ed sectioning format, no one knows.

the best answer for this problem would be changing the structure of
org-latex-classes but I dont want to do that right now.
so I just gave an option for alternative-heading.
