Adobe Captivate 7 - Renaming the "Send"-Button into "Check" Button in exercise questions

Hello,

In my e-Learning project I want to rename the "send" button into "check"-Button on exercise slides. Some exercise slides consist of multiple choice questions, some exercise slides consists of drag and drop questions and some of them consist of connection tasks.

To solve this problem I renamed already the button in two different places:

1. In the project-settings in Adobe Captivate under the menue point "Quiz"

2. On the exercise slides in the window "Settings" under "General" in the field "caption" in Adobe Captivate. 

It is surprising that the new name of this button is shown correct in the program Adobe Captivate. But the old name of the button appears after exporting the e-Learning. Only in the drag and drop exercises the new name is shown correct in the exported e-Leaning.

How can I reach that the "send"-button is named correct as "check" button in all questions in the exported e-Learning?
