Flatlist scroll and scrollview scroll is not working inside modal

I am making filter modal for e-commerce application where I divided it into two component view one for left and one for right view. Where I am using flatlist for left view and scrollview for right.

I am trying achieve scroll on both side. I don't know why isn't working.Same code is working for different project without any problem. I am unable to scroll on either side. Attaching code snippet for same.

              <Modal
      animationType="slide"
      transparent={true}
      visible={this.state.modalVisible}
      onRequestClose={() => {
        this.setState({ modalVisible: !this.state.modalVisible });
      }}
    >
      <View style={Style.general.centeredView}>
        <View style={Style.general.modalView}>
          <View style={Style.general.filterModal}>
            <Text style={Style.general.filterModalHeading}>FILTERS</Text>
            {this.state.filtersApplied.length > 0 ? (
              <TouchableOpacity

                onPress={() => this.clearFiltersHandler()}
              >
