Well that, it turns out that I have fallen a web that uses for all your slider the liquid-slider that I do not even know.
The issue is that one of the slider is giving me a lot of problems.
The link of the slider is this . And the fault appears when we hit the arrow to move from one slider to another, the text with the photo jumps and hides like the image I show. 
I really do not know what solution to give him, I've searched for resources and nothing. I thought it could be a padding or a Margin, but neither could it.
Let's see if you can help me.
P.D: I will try calmly to compile the code, but as I said, it is not made by me and the code is something disastrous.
