[Theme: Blackbird lite]Trying to change the Mobile menu text

For some strange reason it was impossible for me to log onto the theme’s support forum, so I’m posting here hoping someone can help me out.

In the blackbird lite theme I can’t seem to figure out how to change the text being displayed for the mobile navigation drop down menu. “Pages Navigation Menu” is the text that is displayed when the mobile navigation menu is active and I would like to change it to just Menu, but can’t seem to find where the menu is being titled. Any one have any ideas, it would be appreciated, thanks.
