Ahhhhhh thanks Ryan, that makes a total sense! I am new to Foundation so this is a learning curve for me.
Will go and have a play with those grids now, although as XY Grid is default we may just stick with that :)

Ok so tried using "grid-x" instead and this seems to work well. See here for more: https://foundation.zurb.com/sites/docs/xy-grid.html

Also having the same issue, using the very latest download from Github.
Anyone have any ideas on this?
 
Cheers :)
