Ultimate branding Text editor / add Media Issues

I am on the "Help content" trying to add help videos, but I am unable to click the add media button or select text editor, both buttons do not work.

I opened the console and can see an error, can someone please help trouble shoot this issue..

when I click the test editor button I get this error in console:

Uncaught TypeError: Cannot call method 'switchto' of undefined admin.php?page=branding&tab=help:561
onclick admin.php?page=branding&tab=help:561
