Hello everybody

I've been working with the new grid system for the past few days, and now I wanted to add a new row configuration 6 cells, each 2 columns wide which supposed to fit into one row (6 cells x 2 = 12 which is my total number of combined columns inside the row). But the last cells goes into a new row.

Has anybody had the same problem? Also, if you have any suggestions you're more than welcome to share it :)

Greetings
