I have a problem that I have two different trees for buyers and sellers, but for some reason only the buyer tree is displayed.

Moreover, if you go to edit action in the debug menu, the seller tree will be displayed in the seller tab, and the buyer tree will be displayed in the buyer tab, but for some reason the system shows only the buyer tree.

Here is my code:

​id="onova_seller_tree" model="ir.ui.view">
    name="name">Seller list
    name="model">res.partner
    name="priority">30
    name="inherit_id" ref="base.view_partner_tree"/>
    name="arch" type="xml">
        expr="//tree" position="replace">
            default_order='create_date desc'>
                name="create_date" string="Registration date" optional="show"/>
                name="id_site" optional="show"/>
                name="display_name" string="Contact" optional="show"/>
                name="email" string="E-mail" optional="show"/>
                name="phone" class="o_force_ltr" string="Phone number" optional="show"/>
                name="sale_request_count" optional="show"/>
                name="is_partner" optional="show"/>
                name="is_object_partner" optional="show"/>

                name="id_site" optional="show"/>
                name="display_name" string="Contact" optional="show"/>
                name="email" string="E-mail" optional="show"/>
