Post your Event Button Translation

First of all i want to give you my congrats for this great plugin.

Its already spanish translated. But there is one button that it’s not translated, i tryed to use Codestyling Localization , but it’s seems to be already translated in the .MO file.

Can you tell me where can i translate this button.

This the page where i cant translate the button:
