Primary/Main navigation displaying off screen

Primary navigation was displaying correctly (to left) directly under the logo. However, once I added a Revolution Slider the navigation shifted way to the right. I removed Revolution Slider, tried different headers but nothing changes the position of the navigation. Version 1.0 of child theme. Since purchasing the theme I haven’t been notified of any updates. What could be the problem? Thanks. https://imgur.com/a/4u6J3MK
