Looks like specifically the below styling is what is breaking the labels for the fields and for the checkboxes.
IN: /templates/rt_iridescent/css-compiled/master-0329ea5c7b30e2dd4d1e363495af9a02.css
ON: Line 1
Code:
#adminForm label {
width: 100%;
}
Problem is the above is a compressed CSS file so not sure how much the above will help.
