Schedule overlapping navigation menu

Hi there –

I’m having an issue with a the schedule I have on the site overlapping a secondary menu when it scrolls past it. If you look at the page noted, you can see that as you scroll down, the colour time slots scroll on top of the sticky menu that is at the top.

Any thoughts on how to fix that? I’m using WPBakery Visual Composer in the backend.

Thanks.
