Custom Fields Checkbox layout

Hi, I couldn’t find anywhere this has been raised before so if I have missed it I apologise for raising it again.

I am using the supplied Theme and child theme so nothing special being added by myself, however when adding a Multi Select as a Checkbox the layout goes funny as the first checkbox item is displayed correctly to the left of the label field, but then the remaining option (only 5 in total) are left aligned underneath the label and not in align with the first checkbox.

I have checked in Google Chrome and also Firefox and it is doing the same in both of those. If I add a padding-left of 30% then it seems to work but then it messes up the layout of all the description fields for all the other fields.

I will spend more time on it but thought I would raise it incase you didn;t know about it or indeed have a solution.

many thanks
Dean
