Problem with mobile category

[MarcosARMoraes]

Hi,
 

When access the site by mobile phone, on entering category / product (any), the first time is caught without scrolling (I noticed that the bottom is margim-0). If mute product on the page, normalizes (getting regular margin-bottom = 10).

I'm days trying to find the problem, but so far nothing.

One would have no idea what happens?
