mobile view (479 break point) not displaying border radius on image

The community member posted about losing border radius settings when switching to a 479 breakpoint, and affecting the shadow behind it when trying to adjust. The comments suggest that the fields (except color) are adjusted manually for this breakpoint, and hovering over them and resetting them will make them take the setting of a higher breakpoint. Another community member identified the problem as needing to hide the overflow. There is no explicitly marked answer.
