I have installed Commerce Kickstart 2 succesfully, and in the Main (?) menu appears 'Sample Category 1', 'Sample Category 2', 'All Products' .

I can't figure out how to change the titles of these menu options, because on the Menu section says:

"The menu module allows on-the-fly creation of menu links in the content authoring forms. To configure these settings for a particular content type, visit the Content types page, click the edit link for the content type, and go to the Menu settings section. "

When I follow the instructions, the following error appears:

Additional uncaught exception thrown while handling exception.

Anyone can help?
