Writer 3 can't turn off capitalization

Build ID: 350m1(Build:2)

64-bit Ubuntu 12.04

Under Tools → Options → Autocorrect
I have reset the “replace” list, reset the “exceptions” list, and disabled all options, local options, and completions.

However, automatic capitalization after tab and space characters persists. This is happening in a template document (.ott).

I know the Libreoffice software version is “obsolete”, but is there any fix or work-around you can suggest?

A copy of the template document is available if that will help.
