Cs forms checkbox field

Hi there,
i don’t think the settings in the checkbox field are labelled or structured very well. Could the individual elements be labelled more clearly here?
For example, the size of the checkbox. It just says ‘size’.
It’s not entirely clear what size is being referred to here.

Also, I’m missing margin settings for the checkbox. I’ve set the container’s horizontal position to ‘start’. The checkbox moves up but is too high. See screenshot.

Thanks!
