Hi Roch,
Sorry for a late reply. This could generally depend on your theme, but, for example, please try setting priority in “Shop/Category Page Options” section to 9 and then to 11 with “After item” position. With 9 field will be displayed before the “add to cart” button and with 11 it will be displayed after “add to cart” button (i.e. in both cases it’s “after item”, but different position relative to “add to cart” button). Hope you get the idea.
