middleman localizing entire templates not working

Question

I am building a web site using

• middleman 3
• prototype template extension
• en (English language) as default root language

According to this documentation

http://middlemanapp.com/advanced/localization/#toc_6

source/localizable/services.en.html.haml
source/localizable/services.es.html.haml

should generate

build/services.html
build/es/services.html

but bundle exec middleman build generates

build/services.en.html
build/services.es.html
build/es/services.en.html
build/es/services.es.html

I have tried moving both templates to root folder and not working.
