Rev Slider Static Layer Issue

We are using the Revolution Slider as the main landing area of our site at http://www.helpo.com.mx/.

It has 3 moving slides (plain images) and a static layer with content on top.

The problem is that after approx 3 minutes, the static layer disappears. I have set the animation times for them as “from 0 to 99999 seconds” and yet they still disappear after only a few minutes.

Please advise as to the solution

Thanks
