Entry in targets.json appears to be missing opposites field, not sure if it's a bug

        {
                "has_left_and_right": true,

                "targets": [
                    "l-eye-trans-in",
                    "r-eye-trans-out",
                    "r-eye-trans-in",
                    "l-eye-trans-out"
                ]
            },
            {
                "has_left_and_right": true,
                "label": "eye-eyefold-concave-convex",
                "name": "eye-eyefold-concave-convex",
                "targets": [
                    "r-eye-eyefold-concave",
                    "r-eye-eyefold-convex",
                    "l-eye-eyefold-concave",
                    "l-eye-eyefold-convex"
                ]
            }

should the 2nd entry here have the opposites field? seems to me that it should.
