I wouldn't recommend using CSS to adjust this. You can either reformat the column but the reality is to adjust the amount of text. Not a technical solution for sure, but this is one where the product is rendering as it should and has a wrap effect to keep each choice showing together. 

Maybe have the E1, E2 etc with a short phrase or text. Then have a tooltip or explainer underneath to explain more if needed. 

Yes that would be nice if the text was in my control. I still think the wrap should start in the text where it needs to wrap. Not suddenly drop the whole lot onto a new line.
