Material Table icon overlapping with column name

While scrolling down, the icons would overlap with the column name before going out of view. This only happens for the action column.

This is the code for my table column:

    const [columns2, setColumns2] = useState([
    { title: 'Name', field: 'name' },
    { title: 'Surname', field: 'surname', initialEditValue: 'initial edit value' },
    { title: 'Birth Year', field: 'birthYear', type: 'numeric' },
    {
        title: 'Birth Place',
        field: 'birthCity',
        lookup: { 34: 'İstanbul', 63: 'Şanlıurfa' },
    },
]);

const [data, setData] = useState([
    { name: 'Mehmet', surname: 'Baran', birthYear: 1987, birthCity: 63 },
    { name: 'Zerya Betül', surname: 'Baran', birthYear: 2017, birthCity: 34 },
    { name: 'Zerya Betül', surname: 'Baran', birthYear: 2017, birthCity: 34 },
    { name: 'Zerya Betül', surname: 'Baran', birthYear: 2017, birthCity: 34 },
    { name: 'Zerya Betül', surname: 'Baran', birthYear: 2017, birthCity: 34 },
    { name: 'Zerya Betül', surname: 'Baran', birthYear: 2017, birthCity: 34 },

]);

This is the code for the table:

 <MaterialTable
                title="Editable Preview"
                columns={columns2}
                data={data}
                options={{
                    pageSize: 20,
                    search: false,
                    showTitle: false,
                    toolbar: false,
                    thirdSortClick: false,
                    headerStyle: {
                        position: "sticky",
                        top: "0"
                    },
                    maxBodyHeight: "300px"
                }}
                editable={{
                    onRowAdd: newData =>
                        new Promise((resolve, reject) => {
                            setTimeout(() => {
                                setData([...data, newData]);

                                resolve();
                            }, 1000)
                        }),
                    onRowUpdate: (newData, oldData) =>
                        new Promise((resolve, reject) => {
                            setTimeout(() => {
                                const dataUpdate = [...data];
                                const index = oldData.tableData.id;
                                dataUpdate[index] = newData;
                                setData([...dataUpdate]);

                                resolve();
                            }, 1000)
                        }),
                    onRowDelete: oldData =>
                        new Promise((resolve, reject) => {
                            setTimeout(() => {
                                const dataDelete = [...data];
                                const index = oldData.tableData.id;
                                dataDelete.splice(index, 1);
                                setData([...dataDelete]);

                                resolve()
                            }, 1000)
                        }),
                }}
            />

I haven't seen anyone with this problem before, please help. Thank you.
