Conflict with theme layout after adding gallery

Hello, I recently added a gallery to my homepage, but since then, the page layout looks broken. The header and footer are misaligned, and certain elements are not displaying correctly. I’ve tried switching themes, and everything works fine without the gallery, so I think it’s a compatibility issue. Can you help me identify what might be causing this, and if there’s a way to make Robo Gallery work with my current theme?
