Как создать новое представление дерева для res.partner без наследования дерева по умолчанию?

Мне нужно сделать альтернативное древовидное представление для res.partner.

это мой код

<record id="custom_res_partner_tree_view" model="ir.ui.view">
    <field name="name">CUSTOM</field>
    <field name="model">res.partner</field>
    <field eval="1" name="priority"/>
    <field name="arch" type="xml">
        <tree string="Contacts">
            <field string="1" name="custom_field1"/>
            <field string="2" name="custom_field2"/>
            <field string="3" name="name"/>
            <field string="4" name="street"/>
            <field string="5" name="phone"/>
            <field string="6" name="email"/>
        </tree>
    </field>
</record>

.......

<record model="ir.actions.act_window.view" id="custom_res_partner_tree_view_action">
    <field eval="2" name="sequence"/>
    <field name="view_mode">tree</field>
    <field name="view_id" ref="custom_res_partner_tree_view"/>
    <field name="act_window_id" ref="custom_res_partner_action"/>
</record>

Приведенный выше код работает, но ведет себя так, как будто наследует исходное древовидное представление. Он показывает столбцы, которые я не указываю. Как сделать совершенно новое дерево?
