Guys, I found a workaround and, for now, it will work for me. Still it looks a little wonky.
I added the following code:

@media only screen and (max-width:767px) {
     #top .flex_column_table.av-equal-height-column-flextable {
          margin-top: 0px !important;
          margin-bottom: 0px !important;
          padding: 0px !important;
     }
}

I wish I had a more elegant solution.
Any ideas?
