Upper and lower case

Hello,
I have a problem with GTranslate plugin changing the upper case initial letters to lower case when translating a Smart Slider slide button.
Button string “Management Summary” on a German version of the site is translated in English version as a “management Summary” and in French as a “gestion Résumé”.
Why does it change upper case initial letters to lower case at all and can we fix it somehow?
