Read more button issues

I'm working with the Corporate II-template and I installed 2 languages on my Joomla installation (EN/FR both for front and backend), but the readmore-button doesn't change language, it remains in English. This applies to articles and modules as well.
Am I overviewing something or is this some kind of a bug or is there a configuration parameter I missed ?
Thanks for your help.

there is a few places where you can define what to be in the readmore (photoslide and tabs manager...)

Hi

Please show me Your page and point where this READ MORE doesn't change.
