EDITION:
AH OK I GOT IT! my apologies, dint saw that can change page that way, thats cool!. This option should be editable in backend because when you go into responsive on a movil phone, you scroll with the fingers with a little space out of the gallery to "click", and as soon as you pass by the gallery you get stuck in there and trying o scroll it move the gallery over other modules overlapping while it change the page.
I had 3 lines and changed it to one line to give room for the finger and it work ok, thanks
