Please refer to the screenshot, any help appreciated 
This is what you have: a col-xs-6 within a col-xs-6 within a row. What you should have is: 2 col-xs-6 within a row. So the 2 col-xs-6 divs should be on the same level.
Thanks for the help!
Keeping it simple, you must have 2 closed div col-xs-6 before closing the div row.
