@taylornatalierose: Hi, in this moment, I can see that your menu is displayed correctly (in one row). If you still can see it to be displayed incorrectly after reinstalling the theme, please try to refresh your browser or empty cache.
For setting the menu width, please go to “Theme Options > General Settings > Menu Box width”. The sum of values “Menu Box width” and “Title Box width” always should be 100%, because the percentage values are due to the total page width.
For making custom changes in a theme, I can recommend you to create a child theme instead of overwriting the original files.

You’re welcome!
