Toggle help!

Does anyone know why this is happening? It’s really driving me crazy and I can’t figure it out and I’m about to change the design because i can’t figure it out. For Large and Medium, the navigation menu is black text, then a blue box around around the text with text white for active/hover. No problem…

But when i get to the toggle menu and change the links so they are simply black text and change to blue text when active/hover… i get the attached. All links in a horizontal line, plus it bumps up the logo when the toggle is opened. AGH. Thank you in advance.
