Submenu text color not appearing until hover

Hello,

I am new to Beaver Builder, but have generally found it easy to use. I recently added submenus on my website, but when the submenu drops down it is white and the text doesnt show up until you hover over it. The site is www.foundationsft.com Hover over services for the dropdown menu to see what I mean. I have tried searching for answers for hours and tried CSS code but nothing is changing the appearance. Any suggestions?

Thank you!
