I have a paid version of your plugin and it works great apart the responsiveness.
I have a row-layout set to 'full width stretched' (I have the grid butted up to either side). When I load a page it lays out to the edge no problem, but as I re-size the page and the grid resets itself it never hits either edge, their is always a space on both sides of various sizes. Only if I stop and reload the page at a smaller size does it layout correctly when it reloads.
In my layout settings I have a fixed height of 220px, and a 25% width for Desktop and Tablet (100% Mobile).
Am I doing something wrong here? If so can anyone help?
