我正在尝试使用Redux Toolkit按类别过滤数据，例如类型、品牌、颜色、性别。过滤器单独工作，但过滤器不一起工作。如果我先过滤品牌，然后过滤颜色，品牌过滤器不工作。我需要做什么才能使此工作？

const initialState = {
    products: data,
    filteredItems: data,
}

export const filterSlice = createSlice({
    name: "filter",
    initialState,
    reducers: {
        filterCategory: (state, action) => {
            if (action.payload === "All") {
                return initialState
            } else
            state.filteredItems = state.products.filter(
                (item) => item.category === action.payload
            ) 
        },
        filterGender: (state, action) => {
            state.filteredItems = state.products.filter(
                (item) => item.gender === action.payload
            ) 
        },
        filterColor: (state, action) => {
            state.filteredItems = state.products.filter(
                (item) => item.color === action.payload
            )
        },
        filterBrand: (state, action) => {
            state.filteredItems= state.products.filter(
                (item) => item.brand === action.payload
            )
        },
    }
})

我试过在一个reducer中编写过滤器，但仍然不起作用
