How to improve 3rd level navigation selection

I have a responsive dashboard web app, as shown in screenshots. The left navigation menu has two levels of navigation, and then there is a blue tab strip running along the top for the third level. There have been some users who have not noticed that blue strip of tabs. What change might make it more noticeable? I'd currently like to avoid major changes to the layout. Perhaps a color or style change?
