Caxton sections on mobile

Hi there,

I am using the plugin together with some other blocks and encountered a problem when looking at my website on the mobile: The images in the caxtons sections wander off to the right side although I also tried it with no margin on the left side. They just won’t be shown centered on the mobile which bothered me quite a bit.
Help would be appreciated, I am pretty sure, I made a mistake somewhere.
