I tried to inherit the treeview of stock.picking, if I try to modify the inherited treeview and make it editable, this change also occurs on the parent treeview. How can I avoid it? Is there any error in my source?

Thanks in advance

This is my code.

wizard.xml

<record id="shipping_carrier.picktree" model="ir.ui.view">
    <field name="name">shipping.picking.tree</field>
    <field name="model">stock.picking</field>
    <field name="arch" type="xml">
        <tree>
            <field name="name"/>
            <field name="location_dest_id" readonly="1"/>
            <field name="partner_id"/>
            <field name="date" invisible="1"/>
            <field name="min_date"/>
            <field name="origin"/>
            <field name="group_id" invisible="1"/>
            <field name="carrier_id"/>
            <field name="backorder_id"/>
            <field name="state"/>
            <field name="weight"/>
            <field name="priority" invisible="1"/>
            <field name="picking_type_id" invisible="1"/>
        </tree>
    </field>
</record>

wizard.py

@api.multi
def shipping(self):
    return {
        'name'     : _('Delivery Check'),
        'views' : [(self.env.ref('shipping_carrier.picktree').id, 'tree')],
