The in-form REF selection thumbnails/labels are currently cropped by the CSS padding appsheet is applying.
Obviously you want the spacing between the thumbnail and the text label still, so some form of padding must remain. A quick solution may be reducing the thumbnail dimensions from 60x60 to 54x54 to accommodate the 6px padding?
Is this a realistic solution that could happen, or do I need to adjust my images to work within this constraint? It’s sort of unintuitive/annoying, as a deck view thumbnail has an aspect ratio of 1:1, whereas the above REF view is effectively 9:10.
