Submenu white on mobile menu


I have a problem with the Sparkling theme. Links in the submenus will be white in mobile phone. How to solve it?

See attached picture.

Forgot the url:

Solved… the easiest way to remove the green background and white text and added white background and black text. However, sad because the layout could not be maintained.

Good morning

Is everything acceptable for you? can i mark this case as a resolved?
