Some issue with row spacing in VC

I have some issue with the space between the rows in Visual Composer. The space between the rows is very large although I have 0 padding, 0 border and 0 margin in the design options. 

I don't know what it can be, I have checked the theme options in case there was something there but I can't find the solution. What can I can do?
I've attached a capture so you can see it. http://es.tinypic.com/r/14jbxh2/9

I hope I made my self clear.
Thank you.
