xa_sc_category_add_item <-- that template is the Add Item input form
xa_sc_item_edit <-- that template is the Edit Item input form
xa_sc_item_edit_macros <-- that template contains macros used by both of the above input forms.
In this particular case, you will need to edit the title macro's, which are located in the xa_sc_item_edit_macros template. There are 2 macros you will need to edit ('title_item_add' and 'title_item_edit'). You will need to remove the CSS classes on the rowType atribute of the prefixinputrow helper.
Example, here is the 'title_item_add' macro and you will see the red arrow pointing to the rowType attribute. It is using 2 CSS classes (fullWidth and noLable"). Simply remove those 2 CSS classes from the attribute as shown in the 2nd image, then do the same thing for the 'title_item_edit' macro that is the next macro in the template.
