checkbox and radio buttons "edit design" error messages

I have tried to align the labels for checkboxes and radio buttons on several different forms, including templates that you have created that include checkboxes, and whenever I try to set the labels for checkboxes or radio buttons, I get the attached error message. Basically it states that at " line 834 of file ".........WAFB_EditTheme.js: elmSize has no properties. I saw this error in a previous thread, but the advised corrected code is on a different line and my code already has the suggested correction in it. And even when I try to set the properties for checkbox groups under Options/Label placement they have no effect in the "Preview screen" or actual form. I need to align labels to the right and set some other properties with "Edit Design(CSS) / Form Elements / Checkbox".

This is the code in WAFB_EditTheme.js that is causing the problem in all cases:

case "formElementsArea_NoSize":
var elmState = wa.getElements.fieldReference(document.formElementsArea_NoSize.document, "formElementsPage_NoSizeState");
if (!elmState) return;
if (!elmSize.options.length) {
wa.pagesettings.elementSize = wa.pageData.element_sizes[tPage.subAreas[wa.pagesettings.subPage][1].id][0].id;
}
else {
wa.pagesettings.elementSize = $F(elmSize);
}
break;
