but after start and restart service there is no gateway

"subnet4": [
                {
                    "4o6-interface": "",
                    "4o6-interface-id": "",
                    "4o6-subnet": "",
                    "id": 33,
                    "option-data": [],
                    "pools": [],
                    "relay": {
                        "ip-addresses": []
                    },
                    "reservations": [],
                    "subnet": "192.168.33.0/24"
                }
            ],

i update modification_ts in table dhcp4_option and gateway work

"subnet4": [
                {
                    "4o6-interface": "",
                    "4o6-interface-id": "",
                    "4o6-subnet": "",
                    "id": 33,
                    "option-data": [
                        {
                            "always-send": false,
                            "code": 3,
                            "csv-format": true,
                            "data": "192.168.33.1",
                            "name": "routers",
                            "space": "dhcp4"
                        }
                    ],
                    "pools": [],
                    "relay": {
                        "ip-addresses": []
                    },
                    "reservations": [],
                    "subnet": "192.168.33.0/24"
