Revolution slider navigation arrows not working

I have everything set up on for my slider and want to use navigation arrows. When I set up the arrows in WP and use preview mode in WP everything looks perfect. Then I save and go to my website to review and arrows are not there. I moved the placement and got the arrows to show up on the website but they are still not displaying properly. On one of my slide I got the left and right arrows to around the bottom but as the slide moves through each slide the arrows drop lower and lower, eventually the arrows disappear entirely.
